Age Calculator
Calculate your exact age or the interval between two dates.
Calculate Your Age
Enter your date of birth and the date you want to calculate your age at.
How the Age Calculator Works
The calculator compares your date of birth with the selected “age at” date. It first calculates completed years, then the remaining months and days while correctly accounting for different month lengths and leap years.
For total weeks, days, hours, minutes and seconds, the elapsed time between the two dates is converted into the corresponding unit.
