Enter a Gregorian birth date. Keep the calculation date set to your device date or choose another date. Completed calendar years and months are counted before remaining days. See total days and the nearest birthday countdown.
Things to know
Gregorian calendar dates only, without birth time. February 29 birthdays use February 28 in non-leap years. Months are calendar months, not fixed 30-day periods.
