How Does This Age Calculator Work?
This tool calculates your exact chronological age by finding the precise difference between your date of birth and today's date (or any custom date you choose). It accounts for the different number of days in each month and automatically adjusts for leap years, so the result is accurate down to the exact day — not just an estimated year count.
How to Calculate Age Manually
To calculate age by hand, subtract the birth year, month and day from the current year, month and day. If the current day is smaller than the birth day, borrow the number of days in the previous month; if the current month is smaller than the birth month, borrow 12 months from the year.
Example: Born 15 August 2000, today is 4 October 2026. Years: 2026 − 2000 = 26. Months: October(10) − August(8) = 2. Days: 4 − 15 → borrow a month (September has 30 days) → 30 + 4 − 15 = 19. Final age: 26 years, 1 month, 19 days.
Age Calculation for School & Government Forms in India
Many Indian schools, university admissions and government recruitment forms calculate "completed age" as on a fixed cut-off date rather than today — commonly 31st March or 1st April of the admission year, as per RTE Act and various state education norms. Use the "Custom Date" option above and enter the relevant cut-off date to get the exact completed age required for your form.
Chronological Age vs Biological Age
Chronological age is simply the time elapsed since birth — the number this calculator shows. Biological age reflects how your body is functioning based on lifestyle, genetics and health markers, and can be higher or lower than your chronological age depending on fitness, sleep and overall health.

Why Leap Years Matter
A leap year adds one extra day (29th February) roughly every four years to keep our calendar aligned with Earth's orbit around the sun. Ignoring leap years in a manual age calculation can throw off your total day count by several days over a lifetime — this calculator avoids that by using the exact calendar dates under the hood.
Common Uses of an Age Calculator
- Filling school admission, scholarship or government job application forms
- Checking eligibility for exams with minimum/maximum age limits
- Planning birthdays, anniversaries and milestone celebrations
- Quickly finding the day of the week someone was born
- Calculating the exact gap between two important dates or events
