About this tool

“Age as on 31st December” — admission forms, job applications and visa paperwork all ask for your age on a specific date, and doing that sum in your head goes wrong the moment months and leap years join in. Enter your date of birth here and get your exact age, down to the day, for today or for any date the form is asking about.

Alongside the headline figure you get the supporting numbers forms quietly care about: total months, total weeks, total days — and the countdown to your next birthday, which is the one everybody actually opens this tool for twice a year.

How to use the Age Calculator

Enter your date of birth.

Keep the second date as today, or pick the date the form asks about.

Read your exact age in years, months and days.

Questions people ask

Why is my age different from just subtracting the years?

Because your birthday may not have happened yet this year. Subtracting 2005 from 2026 gives 21, but if your birthday is in November and it is only March, you are still 20. This calculator counts the exact month and day, the way official forms do.

Can I calculate age on a future date?

Yes — pick any date in the second field. That is exactly what you need for exam and job eligibility cut-offs that sit months ahead.

Does it handle leap years correctly?

Yes. The calculation uses real calendar dates, so 29 February birthdays and leap years are counted properly.

Is my date of birth stored anywhere?

No. The calculation happens in your browser and the date is not sent or saved.
