Frequently asked questions

Common questions about age calculation and how the tool works.

The calculator counts full years, then full months within the remaining period, then remaining days. For example, if you were born on 15 March 1995 and today is 10 June 2025, your age is 30 years, 2 months, and 26 days. Days in each month are taken into account precisely.

It lets you calculate your age on any date — past or future. By default it is set to today, but you can change it to find out how old you were on a specific historical date, or how old you will be on a future date.

The calculator finds the next calendar occurrence of your birth month and day. If today is already your birthday, it shows a happy birthday message. Otherwise it shows the exact number of days remaining.

Total days is the number of calendar days between your date of birth and the reference date, counting each day exactly once. Total weeks is that number divided by 7 and rounded down. These counts are timezone-safe using UTC date arithmetic.

No. All calculations happen entirely in your browser. Your date of birth is never sent to any server and is not stored anywhere outside your browser session.
