Your exact age and the difference between any two dates.
About Age Calculator
An age calculator finds your exact age from your date of birth — in years, months, and days — and can measure the span between any two dates. Enter a birthday and get a precise breakdown instantly, accounting for leap years and differing month lengths.
Frequently asked questions
- How is exact age calculated?
- It counts full years, then remaining months, then days, correctly handling leap years and months of different lengths — not just dividing total days by 365.
- Can I find the time between two dates?
- Yes. Enter any start and end date to get the difference in years, months, and days.
- Does it handle leap years?
- Yes. February 29 and varying month lengths are accounted for, so the result is accurate.
