Was passed the link to the latest (I think) fan-made version of the MCU timeline, and this one includes dates running from the Jotun invasion of Earth right up to the end of Avengers. The sources are both the movies and all the extra tie-in comics - I personally don't agree with everything in it, and it misses a few things, but I still figure it'll be pretty useful to have things written down so they can used and tweaked.

Enjoy!
