Birthday
Just the digits of month followed by day of a character's birthdate (sorry Europeans, we're using American conventions). While it's tempting to make an entirely new calendar for a fantasy world, we've found that there is just too much confusion from it so we're sticking to an identical gregorian month/date format even if the year counts from after the Reckoning. So if your character was born on March 15, just enter 3/15 for the character's birthdate. Note that this is the character's 'official' birth date, it could be wrong due to secrets and so on.
