Open Age Calculator →📌 What is Age Calculator?
Working out an exact age by hand is fiddly because months have different lengths and leap years shift the count. It matters most for eligibility cut-offs on exam and job applications, where being a few days over or under changes the outcome. This calculator handles month lengths and leap years properly, including dates that fall at the end of a month.
🚀 How to use Age Calculator

❓ Frequently asked questions
Can I calculate age as on a past or future date?
Yes. Change the "age as on" field to any date. This is useful for checking eligibility cut-offs.
Does it handle leap years?
Yes. Day counts use real calendar dates, so 29 February and leap years are handled automatically.
Can I use it to count days between two dates?
Yes. Put the earlier date first and the later date in the "as on" field; the total days figure gives the gap.
How are month-end dates handled?
Dates like 31 January are advanced to the last valid day of a shorter month, which is the standard convention and avoids nonsense results.
