Formula
Age is calculated by subtracting your date of birth from the target date, accounting for leap years and the exact number of days in each month.
Calculating exact age down to the day can be useful for legal forms, medical records, and genealogical research. The age calculator simplifies determining the time elapsed between a birth date and a specific point in time, accounting for leap years and varying month lengths. For more context on how time and dates are calculated universally, check out Wikipedia's page on the Gregorian Calendar.
