25-05-1512. 24-06-1459 - Ezio's birthday. 06-11-1494. 11-01-1165 - Altaïr's birthday? 10-09-1509. 15-06-1511.

The 1509, 1511 or 1512 date may be the birthday of Desmond's next ancestor; Ezio's child.

May be pointing to Desmond no longer being able to synchronize with Ezio; probably has something to do with those dates.
