In the meantime, you can find the Season 10 timeline here, and linked through my Timeline Master Post. Also, I made a few additions to the Pre-series Timeline based on things we learned this year (including how old Bobby was!)
They didn't give me many dates this year, so I do apologize for that - however, it's a bit of a logic puzzle, because I can often tell you how much time has passed between episodes, and how many days are in each episode, so if you really wanted to, you might be able to figure out some dates that I haven't! Or at least approximate them! If you actually want to sit down and try to work it out, and you come up with something with really solid logic, please let me know.
A fun factoid that I discovered while timelining that isn't information I can use on the timeline - Dean's fake IDs have a range of birthdays from 1968 to 1984... meaning that on some of his IDs, he's 11 years older than he is, and on another he's supposedly a year younger than Sam. I thought that was amusing. For the record, the "Freddy Mercury" ID was the youngest, and I think it was the "Lemmy Kilmister" ID that was the oldest.
