Calculate your exact age in years, months and days

This age calculator works out the precise time between a date of birth and today (or any other date you choose). Instead of a rough "about 30", you get the exact number of years, months and days, which is what forms, applications and eligibility checks usually ask for.

Common uses

Checking age limits for jobs, university admissions, exams or competitions.
Filling in government, visa or insurance forms that ask for age on a specific date.
Finding out how many days are left until your next birthday.
Working out the age of a child, a pet, a company or a building.

How the calculation works

The tool counts full years first, then remaining full months, then remaining days, taking different month lengths and leap years into account. That is why the result can differ by a day from simple "divide by 365" methods you might find in a spreadsheet.

Tip: if a form asks for your age "as on" a cut-off date, change the second date to that cut-off instead of today.

Frequently Asked Questions

Why does my age in months not divide evenly?

Months have different lengths (28–31 days), so age broken into years/months/days accounts for calendar irregularities rather than assuming every month is exactly 30 days.

Can I calculate someone's age as of a future or past date, not just today?

Yes — set a custom "as of" date instead of using today's date, useful for eligibility checks, legal age cut-offs, or historical calculations.
