Age Calculator
Find your exact age in years, months and days from your birth date. Free, instant and no sign-up.
How the age calculator works
Enter the year, month and day you were born. The calculator compares your birth date with today and shows your exact age in years, months and days, plus the total number of days you have been alive.
The formula
Age = today minus birth date. The calculator subtracts years, then months, then days, borrowing from the previous month when needed.
Example
Someone born on June 15, 1995 is 31 years old in mid 2026, and the calculator shows how many extra months and days have passed since the last birthday.
Tips
Use the month number from 1 (January) to 12 (December). Check that the day exists in that month, for example February has 28 or 29 days.
