What is Age calculator?
Age calculator gives a precise age for any date of birth on any date – useful for forms, exam eligibility and planning. It handles leap years correctly, including people born on 29 February, whose birthdays fall on 28 February in non-leap years.
When to use it
- Check age eligibility on a cut-off date for an exam or job.
- Fill in forms that ask for age in years and months.
- Count down to a birthday or anniversary.
- Find out which weekday you were born on.
Tips for the best result
- Set the “as of” date to the exam’s cut-off date to check eligibility.
- Totals are calculated from calendar dates, not averages.
- Works for future dates too, e.g. age at retirement.
