Age Calculator
Enter a date of birth and a cut-off date to get the exact age in years, months and days. For a government form, use the "age as on" date printed in that notification — each recruitment sets its own age limits, so this tool shows your age but does not declare you eligible or ineligible for any specific exam.
Everything runs in your browser. Age limits, relaxation rules and cut-off dates differ by recruitment — always confirm them in the official notification for the exam you are applying to.
Frequently asked questions
How is the exact age calculated?
Full years first, then full months, then remaining days, using the real calendar — so leap years and months of different lengths are handled correctly. For example, from 15 January 2000 to 4 November 2026 is 26 years, 9 months and 20 days.
What cut-off date should I use for a government form?
Use the date printed in that recruitment notification — it is often called the "age as on" date and it differs by exam. This calculator does not decide eligibility for you: every notification sets its own minimum and maximum age, so always check the notification itself.
Does this calculator handle leap years?
Yes, with one convention to know: the calculation uses the standard calendar-borrow method for every date (if the day count goes negative, borrow the previous month's days). For a 29 February birthday that method can differ by a few days from calculators that shift the birthday to 1 March in non-leap years — both are conventions, and the total-days figure is exact either way.
