How Age calculator works
Age calculator gives your exact age from a birth date to today, in years, months and days, along with useful extras like the day of the week you were born, the number of days you have lived and the date of your next birthday. It is the precise answer when "I'm 34" is not enough.
The result accounts for leap years and varying month lengths, so the years, months and days match a calendar exactly rather than a raw day count divided by 365. You can also set a custom reference date to find an age at a past or future milestone.
