How the age calculator works
The calculator finds the difference between your date of birth and the "age as on" date. It counts full years, then the remaining full months, then the leftover days — correctly handling months of different lengths and leap years. By default the second date is set to today, but you can change it to find your age on any date (for forms, exams or eligibility).
What you get
- Exact age in years, months and days.
- Totals — your age expressed in months, weeks and days.
- Day of birth — the weekday you were born on.
- Next birthday — how many days until it, and the weekday it falls on.
Frequently asked questions
Does it handle leap years?
Yes. The calculation uses real calendar dates, so leap years and varying month lengths are accounted for.
Can I calculate age on a past or future date?
Yes — just change the "Age as on" date to any date you need.
