This age calculator works out your exact age in years, months and days from your date of birth to today or to any date you choose. Government and private job circulars often ask for your age on a specific date — enter that date in the second box to check whether you are within the age limit.
Checking age for a job application
- Enter the date the circular uses for counting age (for example the application deadline or a fixed date) in the second box.
- If the upper age limit is 30, the result should normally be 30 years, 0 months, 0 days or less. The circular’s own terms always take priority.
- Use the date of birth shown on your SSC or equivalent certificate.
How age is calculated
The calculator first counts complete months from your date of birth and then the remaining days. If you were born on the last day of a month (such as 31 January), the last day of a shorter month counts as a complete month. If your birthday is 29 February, 28 February is treated as your birthday in non-leap years.
Example
Someone born on 15 May 1990 is 36 years, 5 months, 24 days old on 8 November 2026.
Frequently asked questions
Why is another website one day different?
Some calculators also count the end date, and methods for counting days in a month can differ. You can compare using the “include end date” option in the Date Duration Calculator.
