About this age calculator
The calculator reports age as completed years, months, and days. It also shows total completed months, elapsed calendar days and weeks, and the date and countdown for the next birthday. Choose a past date to see how old someone was then; the date of birth must be on or before the calculation date.
Dates are handled as calendar dates, not times, so daylight-saving changes do not affect the results. For a February 29 birthday, February 28 is used in non-leap years.
