How does it work?
Your exact age is not just years: between birthdays there are months and days that count too. This calculator subtracts your birth date from today with real calendar arithmetic.
Leap years are covered: being born on February 29th does not break the calculation. Everything is computed in UTC so your timezone never shifts the result by a day.
Frequently asked questions
Does it account for leap years?
Yes. The calculation uses the real month-by-month calendar, so February 29ths and different month lengths are counted correctly, whenever you were born.
Why does it only ask for the date, not the time?
Because legal and everyday age is measured in full days. The birth time would only matter if you wanted your age down to the hour.
Can I compute the age at a past or future date?
The tool always compares against today. If you need how old someone was on a specific date, use the days-between-dates tool with their birth as the start.
