Roger Bacon: If a game takes place on February 10, 11, and 12, and the person's birthday falls on February 11, that means the game takes place on their birthday. It doesn't mean it's exclusively on their birthday, but it still takes place on their birthday.
ASnakeNeverDies: I disagree wholeheartedly. Frodo's birthday is September 22nd and on that night they have a party before setting out on the quest for Rivendell. If you happen'd to be born the same day as Frodo,
would you say The Lord of the Rings takes place on your birthday? And even then, Cool Spot says "everything in it happens" on their birthday.
That part of it, yes.
