Pick a date of birth to see the exact age.
Formula: age = whole years + whole months + leftover days
- Months are counted from the birth day of the month; if that day doesn't exist (31st), the month's last day is used.
- A 29 February birthday is observed on 28 February in non-leap years.
- Dates use your device's calendar and time zone; nothing is sent anywhere.

- 02Leave the second date blank for today, or pick a date to measure age on, such as a form's cut-off date.
- 03Read the age in years, months and days, the totals and the next birthday.

About this tool
The calculator counts whole years first, then whole months, then the days left over. It also gives the total months, weeks and days lived, the weekday of birth and the number of days to the next birthday. A 29 February birthday is treated as 28 February in years without a leap day.
The "age as on" date is handy for forms that ask for age on a fixed cut-off, such as a recruitment notification or school admission. Leave it blank and the calculator uses today in your device's time zone.
Dates are calculated in your browser and never sent anywhere. For the gap between any two dates that are not a birth date, use the date difference calculator.

Full years are counted from the birth date, then full months, and the remaining days. From 15 Jan 2000 to 9 Nov 2026 that is 26 years, 9 months and 25 days.
How can I find my age on a particular date?
Fill in the "Age as on" box with that date, for example an exam or recruitment cut-off. The result is the exact age on that day.
What if I was born on 29 February?
The next birthday is shown as 28 February in non-leap years. Legal systems differ on whether the birthday falls on 28 Feb or 1 March, so follow the rule of the form you are filling.
Is my date of birth stored anywhere?
