🎂 Age Calculator

About this Age Calculator

The age calculator works out your exact age in years, months and days between a date of birth and any other date, which is today by default. It also shows your total days lived and when your next birthday falls, which is useful for forms, school admissions, jobs and official documents.

How to use it

1. Pick your date of birth.
2. Leave the second date as today, or change it to any date.
3. Click Calculate Age to see the exact result.

Example

Born 15 June 2000 and checked on 15 June 2026: the age is exactly 26 years, 0 months, 0 days, with 9,496 total days lived and the next birthday on 15 June 2027.

Frequently asked questions

Why does the age show months and days too?

Many official forms ask for your exact age on a given date. Years alone can be wrong by almost a full year, so this tool breaks the answer into years, months and days.

Can I calculate age on a past or future date?

Yes. Change the Age at date field to any date and the tool computes the age on that day.

How is the next birthday worked out?

It is the next date with the same day and month as your birth date, counted from the age-at date you selected.
