Age Calculator
What this does
Works out exact age from a birth date to today or to any date you pick — in years, months and days, plus the total in days, weeks and hours. It also shows the next birthday and the day of the week you were born.
When to use it
- Forms that ask for age at a specific date (school entry, insurance, visas).
- Checking eligibility that depends on being over or under an age on a given day.
Good to know
Leap-day birthdays are counted on 28 February in non-leap years, which is what most authorities do.
