Birth date, time and timezone
MM/DD/YYYY

How to use this calculator

Enter your birth date and time, including seconds, in the format selected in the site settings. US uses a 12-hour time with AM or PM; EU and ISO use a 24-hour time. Changing the format keeps the same birth date and time.

Choose the timezone of the place where you were born. It identifies your birth instant and supplies the calendar for years, months, weeks and days. It initially uses the site timezone, but remains independent after the calculator opens. Travelling or changing your current location does not change your age. There is no separate calculation timezone.
