Age Calculator
Enter your date of birth to see your exact age and how long until your next birthday.
How your age is calculated
This calculator counts full elapsed years, months, and days between your date of birth and today's date — the same way you'd count on a calendar, rather than estimating with average month lengths. It also finds your very next birthday and how many days remain until it.
Frequently asked questions
How is my exact age different from just subtracting years?
Simply subtracting birth year from the current year can be off by one if your birthday hasn't happened yet this year. This calculator accounts for that by checking the month and day, not just the year.
What happens if I was born on February 29?
In non-leap years, a February 29 birthday is treated as falling on February 28 for the purpose of counting down to your next birthday.
