The dates for the full moons listed are wrong. For 2011, the dates for full moons were January 19, February 18, and March 19 making Lydia's birthday on March 19th and Allison's before January 19th.
The dates for the full moons in the show are wrong. There's no way to reconcile the amount of time that passes in the show with the actual full moons of 2011.
Curious as to why Lydia's birthday is listed as the 29 when the Worm Moon was the 19. Does the show specifically state that her birthday episode is the 29th or 2 weeks after the prior episode? Otherwise I see no reason why 2x09 couldn't be on the 19th and 2x10 is the next week.
Well it has to be on a Wednesday, so it could maybe be the 22nd. I'd have to go back and watch to see if there are any time references that would place Lydia's birthday more than three days after the night at the club.
The full moon in March 2011 was Saturday the 19th. So not only are the dates off, but so are the weekdays of the dates that are listed.
Full moons occur every 29 or so days, but many of the full moons listed here are every few weeks at most...
The days and timing is off regardless. If you look back at the episodes, you'll notice that this timeline (which I copied from the one the curator had recorded below) is off from the start of the season one section. In the first episode, Scott did get bit the night before going back to school. However, it was after practice the next day (on the first day back), that Scott and Stiles meet Derek and Allison hits the dog. One way you can tell is by their clothing. Scott is wearing the same shirt before school started, the classroom, the hallway, in the woods, and in the animal clinic. Similarly, Stiles was wearing the same outfit before school started, in class, the hallway and when they were in the woods. They never really said what day school had restarted on, but many assume it is a Monday. Due to that, we assume that not much (besides Scott sleep walking) happens between the first day and the day of the party, which is on a Friday.
