Filming dates

Production Filming Schedules

Supernatural takes 8 working days to film an episode. Production runs Monday to Friday. If Episode 1 starts on a Monday, the last day of filming is the following Wednesday and Episode 2 starts filming on Thursday.

Production schedules are fairly rigid for a variety of reasons. Locations must be arranged in advance and permits are needed; guest cast, regular cast, directors and crew must be scheduled. Standard contracts require cast and crew be paid even if production is cancelled. Each day production is running has fixed overhead costs. Jared mentioned in a Convention Q&A that their contracts require that the actors not take the last flight of the day when returning to Vancouver if they're filming the next day. Apparently they can get special permission to violate this rule (he was doing it for this con) but in general even returning from LA for the weekend they have to take an earlier flight than the last one of the day to avoid the risk of them not getting back to Vancouver in time to film the next day.

A normal season has 22 episodes a year. Season 3 was shortened to 16 episodes because of the writers strike; Seasons 7-11 were extended to 23 episodes by the network.

Production begins around the beginning of July and finishes around the end of March. Episodes take 8 weekdays to shoot but that is either 10 or 12 or more calendar days counting Saturdays, Sundays, single day holidays, and longer breaks at Thanksgiving and Christmas. The episodes are aired once a week, so production must start in the middle of the summer to stay ahead of the broadcast schedule even with breaks between airing groups of episodes. Holidays from shooting may include the first Monday of August (British Columbia Day), the first Monday of September (Labor Day), the second Monday of October (Canadian Thanksgiving), the 11th of November (Remembrance day), the entire 4th week of November (US Thanksgiving), 2-3 weeks at the end of December/Jan (Christmas, Boxing Day, New Years), the second Monday of February (Family Day, starting in 2013), and the Friday before Easter (Good Friday) if it falls before the end of shooting.

There is not much public information about the shooting schedule for the early seasons of Supernatural so most dates are based on fan reports, dates encoded in on-set photos, and educated guesses. In later seasons the crew, guest actors, and directors started tweeting during production. Some directors (e.g. Guy Bee) have tweeted pictures of Call Sheets which include 'Day N of 8' along with the date, which makes it definitive when they were shooting. For the first 2/3rds of Season 9 location manager Russ Hamilton was tweeting daily shooting times which was great, but he was apparently told to quit.

The starting time for shooting each day varies depending on when specific locations are available, if shooting at night, or what time filming ended the day before. Standard contracts include specific requirements for overtime/bonus pay if cast and crew are required to work more than a specific number of hours in one day, more than 5 days in a row, or have less than a specific number of hours between the end of one work day and the start of the next. Supernatural doesn't seem to film on weekends nor violate the rest time rules between shooting days, but they do frequently run late on shooting days. To avoid violating the rest period rules, the call times (when crew and actors have to begin work) are often early on Mondays and then if the shooting day doesn't end on time the next day's call times are pushed back (are later). If the call times move back a few hours later each day (a fairly common occurrence, although perhaps not as frequently on Supernatural as on other shows), Friday's call times can be in the afternoon. 'Fraturday' is a common industry slang term for a Friday shooting day that starts so late it doesn't end until the early hours of Saturday morning.

This interview with producer Jim Michaels talks about him joining Supernatural in Season 5, and how long the shooting days were at that time. He said he put a stop to the really long days and said he allows nothing more than 14 hours now (which is still a very long day!) because people needed to have lives outside of work and it was unsafe for folks to drive home from work so tired.

Each episode is directed by a different person. The director generally arrives in Vancouver about a week before their episode is scheduled to begin shooting. They scout filming locations, meet with all the department heads to make choices on wardrobe, sets, props, special effects, stunts, etc. Then they have 8 days of filming, and afterwards they have post-production where they work with the editor on putting the shots together into the finished product, and work with the music editor and video special effects folks. Some directors only work on a single episode, others might do 3-4 episodes over the course of a season.

Filming Dates by Season

The episode numbers below are all based on the original broadcast schedule airing. Where noted, some episodes were shot out of order, so the production numbers may differ. Some were switched after shooting, but some were intentionally shot out of order because of the availability of locations, or because Jensen was directing and needed to shoot first to have preparation time.

Season 1

Filming on the pilot was early in 2005.
Filming for the rest of the season started in July 2005.
Filming ended in early April 2006.

2.21	Late Mar 2007	guess based on the previous episode. No promo pics, although a blogger's set visit seems to point to the fact that they were filming 2x21 and 2x22 together (different scenes from each on different days).

Season 3

Filming started on 17 July 2007.
Filming probably ended sometime early in April 2008.

The Writers Guild of America strike began Monday, November 5, 2007, and ended February 26, 2008. As the strike began, scripts which were already written were allowed to be filmed, but no new writing could be done. After the strike, new scripts had to be written before filming could begin. Supernatural was able to produce 4 episodes after the strike and before the end of the shooting season. 4 episodes is 32 filming days, or a bit over 5 weeks.

Ep #	Filming Dates	Notes
3.01	17 Jul - 26 or 27 Jul 2007	It is announced that season 3 started filming on 17 July. There is a fan report from 20 July that mentions them filming outside the Terminal Pub (sounds like the scene in which the boys and Bobby see Isaac and Tamera enter the pub and then ram through there in Bobby's car to save them). Exif data on promo pics of scene with boys, Tamera and Bobby holed up waiting for the seven deadly sin demons have the date 25 July. Footage from the season 3 gag reel shows scene of Sam walking down the street and being watched by Ruby with a clapboard showing the date 24 July. Comic Con that year is on 27-28 July. Both boys scheduled to attend but Jared misses due to having worked late on a scene (possibly for this episode).
3.02	27 or 30 Jul - 7 or 8 Aug 2007	Exif data on promo pics show the date 30 July. There is a fan report with dated 7 Aug that mentions a restaurant being used as a diner, and the scene with Sam and Ruby is mentioned. Possibly no shooting on 6 Aug (Civic Holiday).

3.04	2007

3.09	2007
3.10	2007
3.11	2007	Filmed after 3.12 but airing order swapped since Jus in Bello was considered to be a better episode to lead into the expected hiatus because of the WGA strike.
3.12	Dec 2007	Last episode written before writers strike. See Supernatural Scrapbook 2007.
3.13	2008
3.14	2008

Season 4

Filming started in July 2008.
Filming probably ended in April 2009.

Both boys did movies over the summer hiatus between Seasons 3 and 4. Jensen did a 3D remake of My Bloody Valentine, and Jared did a remake of Friday the 13th. The movies had their premiers in Jan and Feb 2009 respectively, and the boys had to do publicity and attend the screenings in LA.
Kim Manners died 25 Jan 2009.

4.16	Jan 2009?	Jensen was in LA for his movie premier (My Bloody Valentine 3D) Thurs 8 Jan. Mike Rohl directed both eps 4.16 and 4.18 which is unusual unless the eps were shot out of order. Typically directors don't have repeat episodes closer than 4-5 eps apart. The director usually has a week of prep work (shot prep, location scouting, technical prep for costumes, sets, etc) before shooting a episode, and then additional work a week or two after shooting to supervise editing, sound, etc. Perhaps Kim was scheduled to direct one of these and Mike filled in.
4.17	Jan 2009?
4.18	Early Feb 2009	This fan report said on Mon 9 Feb Jensen filmed all day on this episode, while Jared was in LA for his movie premier (Friday the 13th remake). It also says the crew were wearing small black buttons with KM on them.

The 2010 Winter Olympics were in Vancouver in February 2010, so access to various filming locations was impacted.
The 100th episode of Supernatural was 5.18, filmed in February 2010 and first aired in April 2010.

Season 7

Filming started on 6 July 2011.
Filming ended on 19 April 2012 (well, early in the AM on 20 April).

This is only 7 shooting days. Perhaps they overlapped enough with the previous ep, or they shot with 2 units on the 28th?

So they filmed all the daylight scenes on Sunday (which would have had to be either 4 Mar or 11 Mar) and then overnight on 2 other nights to get the footage they needed.

Tara Larsen made several tweets as production neared the end, that Thursday 19 April 2012 was the last day of filming. (Well, technically the start of the last day of filming, since she also tweeted that they finished at 4am on Friday, 20 Apr 2012.)

Season 8

Filming started on 9 July 2012.
Filming ended on 22 April 2013.

Because 8.03 was filmed first, the production numbers for the first three episodes were not the same as the airing order. The one labeled 8.01 for production aired as 8.03, production 8.02 was 8.01 (the season premiere), and production 8.03 aired as 8.02. This tweet from crew member Janet McCairns joked about the crew confusion with the first three episode numberings.

Ep #	Filming Start Date	Filming End Date	Notes
8.01	Thurs, 19 July 2012	Mon, 30 July 2012	18th was last day filming date of 8.03 (see 8.03 notes). 31st was first filming date of 8.02 (see 8.02 notes).
8.02	Tues, 31 Jul 2012	Fri, 10 Aug 2012	Start date confirmed by a tweet from Kevin Parks. 6 Aug is a British Columbia holiday (B.C. Day), confirmed by a tweet from Tara Larsen, and a tweet from Clif Kosterman. A tweet from Russ Hamilton confirms Wednesday, 8 Aug is day 6 of 8.
8.03	Mon, 9 Jul 2012	Wed, 18 Jul 2012	Jensen directed again. His episodes film first so he has time to do prep, but this was the third episode of the season. There were several tweets from the first day of filming, including a tweet from Kevin Parks, a tweet from Russ Hamilton, a tweet from Jim Michaels, and a tweet from Tara Larsen. Ending filming date was tweeted by Kevin Parks.
8.04	Mon, 13 Aug 2012	Tues, 21 Aug 2012	Computed days from end of 8.02 to start of 8.05. Because of the very different shooting style of this episode, apparently they took only 7 days for this ep.
8.05	Wed, 22 Aug 2012	Fri, 31 Aug 2012	This tweet from Director Guy Bee said he would start shooting on the 22nd. Guy tweeted a photo of the Day 1 of 8 call-sheet on Aug 22nd. (The call-sheet says shooting start time for Day 1 is noon and "lunch" is at 5pm.) Kevin Parks tweeted it was Day 6 on Wed, 29 Aug. Tara Larsen posted a tweet on Friday, 31 Aug that it was the last day for this episode. Guy tweeted another photo of the Day 8 of 8 call-sheet on the Aug 31st (with a shooting start time for Day 8 of 3:00pm and "lunch" at 7pm).
8.06	Tues, 4 Sep 2012	Thurs, 13 Sept 2012	Monday 3 Sept was a holiday for Labor Day. Tara Larsen tweeted on Tuesday 4 Sept that they were starting shooting. Another tweet from Tara Larsen said 13 Sept was the last day of shooting for this episode.
8.07	Fri, 14 Sep 2012	Tues, 25 Sept 2012	This tweet from someone at the Dallas convention on 23 Sept says Jared said they have two more days to film on this ep, which would make the last day 25 Sept. This tweet from Amanda Tapping said the 21st Sept was her first shooting day. Jensen told a story at the Dallas Con about the wind machines used in the scene when he got out of purgatory and that it was shot on 17 Sept.
8.08	Wed, 26 Sep 2012	Fri, 5 Oct 2012	Assuming an 8 day shooting schedule. This tweet from Jim Michaels on 3 Oct says that at the end of today they are 1/3 of the way through shooting season 8. 23 episodes * 8 days - 1 for the strange schedule of 8.04 (7 days apparently, or overlapped shooting) means the season has 183 shooting days, and 1/3 is 61 days completed. That would make Oct 3rd be day 6 of 8 for this episode. This tweet from Jim Michaels said they are going to be working with Mike Farrell. This tweet from Tara Larsen contains a photo of the episode number (8.08) along with the episode title.
8.09	Tues, 9 Oct 2012	Thurs, 18 Oct 2012	Second Monday in Oct (8 Oct) is Canadian Thanksgiving. On 17 Oct Jim Michaels said in a tweet that they were shooting 8.09.
8.10	Fri, 19 Oct 2012	Tues, 30 Oct 2012	doing the math with 8 day shooting schedule and no breaks. Several tweets during this time mentioned scouting and casting for the next episode (8.11).
8.11	Wed, 31 Oct 2012	Fri, 9 Nov 2012	This tweet from Jim Michaels confirms 31 Oct was the first day of shooting this episode. Guest star Felicia Day (@feliciaday) tweeted on Halloween (the first day) and again on 5 Nov that she was working on her episode.
8.12	Mon, 13 Nov 2012 (thru Fri, 16 Nov)	Thurs, 29 Nov 2012 (from Mon, 26 Nov)	This tweet from Jared confirmed Tues 13 Nov was day 1 of ep 12. Several tweets from Kevin Parks mention the long weekend (Mon 12 Nov was a holiday), and a tweet from Clif confirmed they are taking all of (American) Thanksgiving week off (19-23 Nov this year). So for this episode, 4 days were before the break, 4 days after. A tweet on Monday, 26 Nov from Jerry Wanek confirmed they were back at work.
8.13	Wed, 12 Dec 2012	Fri, 21 Dec 2012	Episodes 8.13 and 8.14 were shot out of order (8.14 first) so tweets relating to this and the next episode can be confusing. The production numbers are different from the airing order numbers (which is what is listed here.) Several tweets about Fri 21 Dec being the last filming date before the Holiday break, including this one at 3 mins past midnight from Russ Hamilton. This tweet from Werner ten Hoeve (@wern_r) and surrounding tweets talk about the visual effects they are doing for this episode and about the reverse in the order. This tweet from Jim Michaels said they had unexpected snow in the episode directed by Phil Sgriccia, which confirms this episode was shot after ep 8.14.
8.14	Fri, 30 Nov 2012	Tues, 11 Dec 2012	This episode was shot before 8.13 but aired as 8.14. This tweet from Tara Larsen on 30 Nov said it was the first day of the new episode and contains a photo of director Kevin Parks. This tweet from Jim Michaels said it's Day 1 of the next episode. Another tweet from one of the crew with a slate marking Scene 1 of the episode. In this tweet and this followup tweet producer Jim Michaels said they've never shot the opening scene of the episode as the first shot of the first day before. (Scenes are generally filmed out of order for time, availability of locations or actors, etc.) This tweet on Mon, 3 Dec said they're shooting Day 2. This tweet on Tues, 11 Dec said they were shooting the last day of this ep.
8.15	Tues, 8 Jan 2013	Thurs, 17 Jan 2013	This tweet from Russ Hamilton said Tues 8 Jan was the first day of 8.15. Both Js went to the People's Choice awards in LA on Wed 9 Jan. Kevin Parks tweeted early (6am) on Fri 11 Jan that it was going to be a Fraturday, so apparently they made up for the lost filming time for the PCAs. This tweet on Wed 15 Jan from Clif said the boys were getting over the flu. Jared's voice is noticeably lower in several scenes.
8.16	Fri, 18 Jan 2013	Tues, 29 Jan 2013	This tweet from Russ Hamilton said Fri 18 Jan was the start of 8.16.
8.17	Wed, 30 Jan 2013	Fri, 8 Feb 2013	Doing the math from start of ep 8.16 to start of ep 8.18. This video of Jensen (with Jared in the car) backing down the street to reset for the next shot, was filmed 5 Feb.
8.18	Tues, 12 Feb 2013	Thurs, 21 Feb 2013	Second Monday in Feb is a BC holiday. This webpage says Jensen said they had a 3 day weekend with Monday off. Tweet from Russ Hamilton on Tues 12 Feb said this was Day 1 of this ep. This tweet from Jim Michaels on Tues 12 Feb said there were 47 more shooting days in this season after today. That would be 8 days * 5 eps left, plus 7 more days on this ep.
8.19	Fri, 22 Feb 2013	Tues, 5 Mar 2013	The photo in this tweet from the director of 8.19 shows in the small print that shooting on this episode starts Fri 22 Feb. Several tweets by the director confirm the dates. This tweet confirms Tues, 5 Mar is Day 8 of 8. The Harlem Shake video was filmed during the shooting of this episode.
8.20	Wed, 6 Mar 2013	Fri, 15 Mar 2013
8.21	Mon, 18 Mar 2013	Wed, 27 Mar 2013	This tweet from the (spoiler) director says 27 Mar is the last day of his episode.
8.22	Thurs, 28 Mar 2013	Tues, 9 Apr 2013	Production has Good Friday off if Easter happens before the end of filming. In 2013 that's Friday, 29 March. Author S.E. Hinton was visiting the set during the filming of this ep. Her tweets and pics are storified here by @Superwiki.
8.23	Wed, 10 Apr 2013	Mon, 22 Apr 2013	Jim Michaels said at the Con in Rio 2012 that the CW asked for 23 episodes again in Season 8. The Season 8 Wrap party was Saturday night, 13 Apr 2013. Many tweets and pics from the party, storified here by @Superwiki. This tweet from Russ Hamilton says Monday 15 April is Day 4 of shooting this episode, but that the last day of filming would be Monday, 22 April, which would mean 9 shooting days on the season finale. This tweet from Russ on Monday, 22 April, says it's the last filming day. This tweet (and the rest of the twitter conversation) from Kevin Parks says the last filming date for the J's was Thursday, 18 April. Misha and the rest of the cast and crew filmed until Monday.

Season 9

Filming started on 11 July 2013.
Filming ended on 25 April 2014.

Supernatural was renewed for Season 9 on Monday, 11 Feb 2013.
On 6 June 2013 producer Jim Michaels confirmed with this tweet that Season 9 would again have 23 episodes.
Because of wanting to spend time with his family Jensen has said he didn't want to return from hiatus early to direct the first episode to be shot. He said he is still interested in directing but because of the prep work it would be hard to do during the season. It might be possible for him to direct right after a break - like at Christmas - although one suspects he still might prefer more family time.
According to the BC Film Commission website for production schedules of TV shows and movies filming in Vancouver, Supernatural's 9th season will be shooting from 11 July 2013 to 24 April 2014.
This tweet from one of the crew (and another by Jim Michaels) both say there are 184 shooting days in this season. That's 23 episodes times 8 days each.
Figuring out filming dates had been dead easy this year, up until February, because Russ Hamilton, aka @Russ_MOVIEGOD on twitter, had been tweeting the crew call and camera wrap times for each day of filming, along with the episode number and date. No detective work needed. Apparently he was told to stop, so the last 7 eps of the season needed other clues, and was complicated by the filming of the spinoff pilot, including filming days in Chicago.

Ep #	Filming Start Date	Filming End Date	Notes
9.01	Tues, 23 Jul 2013	Fri, 2 Aug 2013 **	This tweet confirms the start date for this episode and that 9.02 was shot first and 9.01 second. ** This tweet from Russ Hamilton says that a 2nd unit filmed 9.01 scenes on Fri, 2 Aug, while the 1st unit filmed the start of 9.03 on the same day. (Note the screwy numbering because of swapping 9.01 and 9.02 in shooting vs airing order.)
9.02	Thurs, 11 Jul 2013	Mon, 22 Jul 2013	Supernatural started filming Season 9 on the 11th of July, confirmed by this tweet from the (spoiler) director, and source 1, source 2. On 25 June location manager Russ Hamilton tweeted about his first day of prep for Season 9. @Superwiki storified it here. Several tweets, including ones from Jim Michaels confirm that the first episode to be shot will NOT be the season premiere. (This tweet from Serge confirms episode 9.02 was shot first, 9.01 second.) Jared, Jensen, and Misha went to San Diego Comic Con 2013, including a Supernatural Panel on Sunday, 21 July source. This tweet from Jared on Friday, 19 July shows him at the San Diego Zoo, and this tweet says Warner Brothers surprised him with a Birthday cake at the WB Party Friday night. Misha was also at Comic Con on Friday (see this tweet with him and John Barrowman). This tweet (at 3am! Fraturday) from the director confirms Friday was day 7 of 8, and that they continued filming anyway without 'the boys' (which implied Jensen left Vancouver early, too, although he wasn't seen in San Diego on Friday.) This tweet confirms Monday 22 July was Day 8 of 8 and includes the (spoiler) episode name. It is production number 9.01, but will air as episode 9.02.

Russ tweeted that Thurs, 21 Nov, was exactly 1/2 of the way through filming Season 9 (shooting day 92 of 184). Russ tweeted that there was a Day 9 for this ep, so 5 Dec had filming for both this and the following episodes.

This tweet from Russ on 21 April said there were 4 more shooting days left after Monday. This tweet from Russ on Friday, 25 April confirms this is the last shooting day of season 9. There was an earlier tweet from Jim Michaels which said Thurs, 24 April was day 184 of 184, and that seems to be the boys last filming day (tweet from Jared Thurs night, fan report of Jensen flying home on Friday), but they did continue to film on Friday, 25 Apr until 3:22am (Saturday), according to this tweet from Russ. Also, Kevin Parks confirmed Friday filming in this tweet. If they did film on Monday, 21 April (which could have been a holiday for Easter), that would make Thursday Day 8, and Friday Day 9. The Season 9 wrap party was Saturday night, 26 April, with many tweets from the crew including Jim Michaels, Russ, Adam Williams and many others.

Season 10

Filming started on 8 July 2014.
Filming ended on 21 April 2015.

Supernatural was renewed for a 10th season on 13 February 2014.
The first episode aired in the US on Tuesday, 7 October 2014.
Episode 10.05 was the 200th episode of Supernatural, shooting in August 2014 and airing in November 2014.
(The 100th episode was 5.18, filmed in February 2010 and first aired in April 2010.)
Jensen directed again this season. His episode filmed first but aired as 10.03.
Assistant production coordinator Jason Fischer tweeted this picture showing an expected 184 filming days. That means 23 episodes again this year. (184 days / 8 days/episode = 23 episodes. See, math can be useful!)

Ep #	Filming Start Date	Filming End Date	Notes
10.01	Fri, 18 July 2014	Tues, 29 July 2014	J&J were at the TCA (Television Critics Association) Press Tour in LA on Friday, 18 July.

10.02	Wed, 30 July 2014	Mon, 11 Aug 2014	No filming on Monday, 4 Aug (holiday for British Columbia Day). This tweet from Jason Fischer mentions the long weekend.

This tweet from a fan at the location shows how they dressed that place up. This tweet from Russ Hamilton confirms 1 Aug is Day 3 of 8 for this episode. (Note that he's using filming numbers for the episodes, not airing numbers. This ep is filmed third, will air second.)
10.03	Tues, 8 July 2014	Thurs, 17 July 2014	Jensen directed this episode. They filmed it first so he had the week before filming to do prep, but the ep will air third.

10.10	Tues, 21 Oct 2014	Thurs, 30 Oct 2014	Dates computed from the previous ep end and next ep start.
10.11	Fri, 31 Oct 2014	Wed, 12 Nov 2014	Starting date confirmed by this tweet (director spoiler) from Kevin Parks. No filming Tues, 11 Nov (Remembrance Day holiday). The boys and Misha were in LA on Tuesday, Nov 4th, for the 200th Fan Appreciation Party. Mark Sheppard was in Vancouver shooting, according to this tweet.
10.12	Thurs, 13 Nov 2014 (thru Fri, 21 Nov)	Mon, 1 Dec 2014 (from Mon, 1 Dec)	Starting date confirmed by this tweet (director spoiler) from the director's wife. Friday 21 Nov is day 7 of 8. Production usually takes the week of American Thanksgiving off, leaving day 8 for 1 Dec. As in recent years, one of the local crew is directing this episode so an LA director doesn't have to fly back in for one day of filming after the break. Last day of filming on 1 Dec confirmed by this tweet from the director.
10.13	Tues, 2 Dec 2014	Thurs, 11 Dec 2014	This tweet from Kevin Parks confirms 3 Dec was day 2 of 8 for this episode. (Also that his dog Kuma might be in a shot - which turned out to be true. Photo evidence in this tweet.) On 9 Dec Jensen tweeted this pic of the Croissookie.
10.14	Fri, 12 Dec 2014 (thru Fri, 19 Dec)	Wed, 7 Jan 2015 (from Tues, 6 Jan)	Production usually takes 2 weeks off at Christmas/New Years. After the break often the production folks start on Monday and filming doesn't begin until Tuesday. This tweet from Russ Hamilton confirms that Monday 5 Jan was a prep day and filming of day 7 of 8 of this episode began on Tues, 6 Jan. Also, this tweet from production assistant Jason Fischer confirms 7 Jan is Day 8 of 8.
10.15	Thurs, 8 Jan 2015	Mon, 19 Jan 2015 (guess)	This tweet from Jim Michaels on 15 Jan 2015 says it was Day 5 of episode 10.15. Yet, this tweet from Jason Fischer confirms that 12 Jan is day 115 of the season, which would be Day 3 of Episode 15. Either Jim is off by a day, or perhaps they filmed past midnight, or there was a day off from filming between the 12th and 15th that they made up later somehow.
10.16	Tues, 20 Jan 2015 (guess)	Thurs, 30 Jan 2015	This tweet from Jim Michaels celebrated that they were starting filming at 9:00am on a Friday, which meant no late filming on a Friday night (no 'Fraturday'). This tweet from Jason Fischer says they were working on both eps 16 and 17 on 30 Jan. Either day 8 or 9 for ep 16.
10.17	Fri, 30 Jan 2015	Wed, 11 Feb 2015 (guess)	No filming on Mon, Feb 9th (Family Day holiday in BC). Several of the crew tweeted about the day off from work. Start of this episode confirmed by this tweet from Kevin Parks.
10.18	Thurs, 12 Feb 2015 (guess)	Mon, 24 Feb 2015	This tweet from production person Jason Fischer says they were shooting second unit scenes for episode 18 and main unit scenes for episode 19 on 24 Feb.
10.19	Tues, 24 Feb 2015	Thurs, 5 March 2015	This tweet from Jason Fischer implies that 24 Feb is the first day of this episode. Ending date confirmed in this facebook post by Jared.
10.20	Fri, 6 March 2015	Tues, 17 March 2015 (guess)
10.21	Wed, 18 March 2015 (guess)	Fri, 27 March 2015 (guess)
10.22	Fri, 10 April 2015 (guess)	Tues, 21 April 2015	The finale was filmed first, so the last day of the season is at the end of filming this episode. Last day of filming confirmed by many tweets, including this one from Serge, and this one from Jason Fischer.
10.23	Mon, 30 March 2015	Thurs, 9 April 2015 (guess)	The finale was filmed before ep 22, according to tweets from Jim M, and Jared at SeaCon. This meet and greet report from SeaCon (warning: spoilers for guest star name) says the order swap was to accommodate the guest's schedule. No filming on Fri, 3 April (Good Friday holiday). On Thurs, 9 Apr, Russ Hamilton sent this tweet saying they were filming with two full units on this day, and by doing the math he confirmed that Tues, 21 April is the last day of filming.

Season 11

Supernatural was renewed for a 11th season on 11 January 2015.
Filming began 7 July 2015 and ran through 19 April 2016.

This tweet from Tammy Barker confirmed Tues, 19 Apr 2016 was the last day of filming for Season 11, also this tweet from Emily Swallow (the Darkness), and this tweet from production person Jason Fischer.

Season 12

Supernatural was renewed for a 12th season on 11 March 2016.
Filming should begin sometime in July 2016 and run through April 2017.
Possibly Season 12 will start on Mon, 11 July 2016 -- based on 2 tweets at the end of Season 11 saying they had 82 days from the end of Season 11 to the start of Season 12. But often the production office opens one day before actual filming starts, so filming could begin on Tues, 12 July.
