I found this March 16th date in X2 (top left corner). I used this date to place the second movie in my version of the timeline. X1 has to be early November to avoid it being in the complete dead of winter.
I don't know if anyone here has read the novelisations of the first 2 movies but heres what I found in regards to the timeline. The X1 novel repeatedly refers to the time period as being winter, it also describes Jean as being in her early 30's. The X2 novel refers to the first movie multiple times as having happened 'months ago'. It also said that the night Mystique injects the guard with iron was a Saturday. We know this happened the night before Magneto's prison escape which is where the March 16th date was found. This would therefore make it Sunday March 16th which fits perfectly in 2003.
