I added it to the S6 Timeline, so don't get confused...just scroll down.
You can find out what Sam did on his birthday, what day the horrible events of the finale happened, or what things didn't occur in May of this year!
I also made a few small additions to my pre-series timeline, and one addition to my S1-S5 timeline.
Unfortunately, because my S1-S5 timeline is so goddamn huge, I can't add anything more to it unless I split it into two posts...which, I suppose I could do, but...do I have to? As of right now, I've added the Repo Man information into the S3 timeline and explained that it could also go in S4. It's not ideal, but odds are they won't be giving us any more information about previous seasons and this won't ever happen again. Plus, i just really think that flashback took place in S3. :P
Anyway, I've learnt my lesson on huge timeline posts - so next year S8 will get a fresh post of it's own. It'll work out nicely - I'll have Kripke's run as showrunner in one massive post, Sera's in another, and then Jeremy Carver's!
(Having a new post for S8 also works out, because I've noticed that as time passes, I get wordier and wordier in my explanations. I COULD take out some of the notes explaining how I did things; but, honestly, I think it's important for people to know what logical leaps I am making. Also, I've realized that it's important for ME to know, so that if something in the future contradicts what I have, I know right away how I arrived at the date...and if I'm going to have all that information on file, I might as well include it.)
So, as usual, please have a look over and see if I've messed anything up. I used a lot of episode-relational-proxy-dating this time around, because often I could tell how much time had passed between episodes - so once I had a date for one, I could include approximate dates for the others.
