Frequently Asked Questions

How do I check my age eligibility for a government exam?

Select "A specific date" and enter the exam notification's cut-off date — the calculator shows your exact age as on that date, in years, months and days.

What is the formula for calculating age?

Age is calculated by finding the difference in years, months and days between the date of birth and the reference date, adjusting for varying month lengths.

Is my date of birth stored anywhere?

No — the calculation happens entirely in your browser and nothing is stored or shared.

Can I find out how many days until my next birthday?

Yes — the results include a "Days To Next Birthday" stat, calculated from today's date regardless of which "as on" date you chose for the main age calculation.
