George Harrison's birthday is coming up in a few days--but exactly when is it? For most of George's life, he thought he was born on February 25th, but family documents later shown he was born on February 24th--at ten minutes to midnight. However, if you look at official online biographies for George, they all list February 25th. I guess the best thing for a devout Beatles fan to do is hold a two-day celebration for George.
While there are real-life instances where someone claims to have been born in a different year, I'm hard-pressed to think of an example where someone changes the date. The best example from fiction I can think of is from my own work. The mother of one of the Season Avatars deliberately registered her daughter with a false birthday to hide her magic potential from her father. (More details are available in Scattered Seasons.) I suppose other fictional reasons for hiding one's true birthday would be to change when one is or isn't ready for school or the draft. It could also be part of a larger plan to disguise one's identity.
Have you ever come across someone who found out later in life that they'd been celebrating the wrong birthday? If you had the chance, would you want to move your birthday, and if so, why? Feel free to share in the comments.
