How the Calculation Works
Enter your date of birth. The calculator uses the calendar-based method to compute completed years, remaining months, and remaining days from your birth date to today. It also calculates the total number of days you have been alive (including leap days), total hours, and total minutes. The day of the week you were born is determined from the birth date.
