About the Age Calculator
Enter a date of birth to see an exact age in years, months and days. You can also change the “age as on” date to find age on a past or future date, which helps with forms and eligibility checks.
How to use it
- Pick your date of birth.
- Leave the “age as on” date as today or choose another date.
- Read your age, total months, weeks and days, and the countdown to your next birthday.
Frequently asked questions
- Can I calculate age on a specific date?
- Yes. Change the “age as on” field to any date on or after the birth date.
- How are leap-year birthdays handled?
- The tool counts calendar months and days, so a 29 February birthday is treated as 1 March in non-leap years for the countdown.
