Your exact age, to the day

Enter your date of birth and the tool gives your precise age in years, months, and days, your total days alive, and a countdown to your next birthday. You can also set a different "as of" date — handy for official forms with age cutoffs.

Worked example

Someone born on 15 June 1995 is, on 25 July 2026, exactly 31 years, 1 month, and 10 days old — about 11,363 days. Their next birthday is on 15 June 2027.

Why day-exact age matters

Many rules hinge on your age on a particular day: exam eligibility, sports age groups, child fares, retirement dates, and legal thresholds. Calendar-accurate counting (rather than dividing days by 365) is what makes the answer correct across leap years and different month lengths.

Frequently asked questions

+How is exact age calculated?

The calculator counts full calendar years from your birth date, then full months, then remaining days — the same way official documents do. It correctly handles months of different lengths and leap years.

+What if I was born on February 29?

In non-leap years, your calendar birthday doesn't exist; most conventions (and this tool's next-birthday countdown) treat March 1 as the day your age ticks over, while some countries use February 28.

+Why do the months and weeks figures say 'approximately'?

Your age in years/months/days is exact. The single-unit conversions (total months, weeks, hours) are derived from whole days, so they're rounded for readability.

+Can I calculate age at a date other than today?

Yes — change the 'age at date' field to any date, past or future. This is useful for forms that ask your age on a specific cutoff date, like school enrollment or visa applications.
