Sometimes we want to know exactly how old we were on a specific, important day in the past. It could be a historical event, the day we met someone significant, or simply a moment when we want to determine our precise age.
How do you calculate your age in the past? Simply use our age calculator. In the “Your Date of Birth” field, enter your birth date, and in the “Date to Check” field, enter the specific past day you’re interested in.
