Find your exact age in years, months and days from your date of birth.
This age calculator tells you your exact age in years, months and days from your date of birth — plus total months, days and hours lived. It's free, instant and works on any device.
Your age is the elapsed time between your date of birth and today. The calculator counts complete years first, then the remaining months, then the leftover days — correctly handling months of different lengths and leap years (which add 29 February every four years). This is more accurate than simply subtracting the birth year, which ignores whether your birthday has occurred yet this year.
Enter your date of birth and the tool instantly shows your exact age in years, months and days.
Yes — change the second date to any date to see your age on that day.
