How age is calculated

Your age is simply the time elapsed between your date of birth and today. The tricky part is expressing it in years, months and days, because months have different lengths and leap years add an extra day every four years. This calculator handles all of that:

  1. Full years are counted first (subtracting one year if this year's birthday hasn't happened yet).
  2. Then full months since the last birthday are counted.
  3. The remaining days make up the final part of your age.

Where you need your exact age

  • Government job applications — most Sarkari Naukri posts specify age limits "as on" a cut-off date.
  • Competitive exams — UPSC, SSC, banking and railway exams all have strict age eligibility.
  • Official documents — passport, PAN and Aadhaar forms sometimes ask for age in years/months/days.
  • Insurance & pensions — premiums and eligibility often depend on completed years of age.

Frequently asked questions

How is age calculated if my birthday hasn't occurred this year?

The calculator automatically subtracts one year and counts months/days from your last birthday, so the result is always correct regardless of today's date.

Does it account for leap years?

Yes. The day count uses real calendar math, so 29 February birthdays and leap years are handled accurately.

What does "age as on a specific date" mean?

Many applications ask your age on a cut-off date (e.g. 1 January). This tool calculates as of today; for a cut-off date, count forward or backward from today's result.
