Age Calculator
Find your exact age in years, months, and days from any birth date.
How it works
Enter your date of birth and the calculator instantly shows your exact age in years, months, and days. It also displays your age in total days, weeks, and months, plus how many days until your next birthday.
How age is calculated
The calculator subtracts the birth date from today's date, accounting for varying month lengths and leap years. Days are counted from the birth date up to but not including today.
