About Age Calculator
This tool helps you calculate your precise age based on your date of birth. In addition to years, months, and days, we also display the total number of days you have lived and a countdown to your next birthday.
How is age calculated?
The manual formula is simple: Subtract your birth date from today's date. If the current day/month is smaller than the birth day/month, borrow the number of days from the previous month or the number of months from the previous year.
FAQ
