The birthday of each football players in FIFA Manager 12 stores in a fashion of Julian Date. Since AD 1585, we've used Gregorian Calendar. So the stored value is very strange.
For example, a player was born in 1984. 7. 21.
Generally, it stores as decimal value 30844. This value means the elapsed days from AD 1600.1.1. But in FIFA Manager 12, stores 2445903. It means the elapsed days from AD 0.1.1.
If you edit a player's stat with in-memory-value editing, you must consider this fact.
