Is birthdate information stored?

No. All age calculations execute in your browser memory and are never saved or transmitted.

Can I calculate age on a date other than today?

The calculator uses today's date. Use the Date Difference Calculator to measure between any two dates.

How is age counted when I was born on 29 February?

In non-leap years, your birthday is counted as 1 March.

Why does my age in months look off by one?

A month only counts once the same day of the month is reached. On 14 March, someone born on 15 January is 1 month and some days old, not 2 months; the second month completes on 15 March.

About Age & Milestone Calculator

Calculate an exact age in years, months, and days from a date of birth, along with total days and weeks lived and a countdown to the next birthday.

How age is counted

Age is counted in completed years, then months, then days, the same way it appears on official forms. Someone born on 15 March 2000 is 25 years old from 15 March 2025 until the day before their next birthday.

For people born on 29 February, the next birthday in a non-leap year falls on 1 March in this calculator.

Milestones

Total days lived is a fun way to spot milestones like your 10,000th day, which falls a little after age 27. The birthday countdown shows how many days remain until the next one.

Your date of birth is not stored or sent anywhere; the calculation happens in your browser.
