How is age calculated?
Your age is the time elapsed between your date of birth and today (or any chosen date). This calculator counts complete years first, then the leftover months, then the remaining days — the same way we naturally say "32 years, 4 months and 12 days".
Fun extras
It also shows your total days and hours lived, the day of the week you were born, and a countdown to your next birthday — handy for planning celebrations.
Does it handle leap years?
Yes. The calculation uses real calendar dates, so leap years and different month lengths are accounted for automatically.
Why might my age look off by a day?
Time zones and the exact time of birth can shift a day. This tool uses calendar dates at midnight.
