Common questions
How do I calculate my exact age?
Enter your date of birth above and the date you want to calculate your age on (defaults to today). The calculator shows your exact age in years, months, days, hours, and minutes.
How old will I be on a future date?
Enter your birthday, then change the "calculate age as of" date to any future date. The calculator will show exactly how old you'll be on that day.
How old was someone who was born in the past?
Enter their birth date and set the "as of" date to any historical date to find out their age at that point in time.
Does the calculator account for leap years?
Yes — the calculator handles leap years automatically, so your age calculation is always accurate regardless of whether your birthday falls on February 29.
