Age Calculator
Calculate your exact age in years, months, days, and total days from your date of birth.
The Age Calculator computes your precise age from your date of birth. It shows your age broken down into years, months, and days, plus the total number of days and weeks you have been alive.
How It Works
Enter your birth year, month, and day. The calculator determines your exact age as of today, accounting for leap years and varying month lengths. It also tells you how many days remain until your next birthday.
What It Calculates
- Years, Months, Days: Your age in the familiar format (e.g., 35 years, 9 months, 3 days)
- Total Days: The exact number of days since birth, including leap days
- Total Weeks: How many complete weeks you have lived
- Next Birthday: Days remaining until your next birthday
This calculator is useful for legal age verification, milestone tracking, and anyone curious about their exact age in various units. It properly handles leap years (divisible by 4, except centuries unless divisible by 400).
Frequently Asked Questions
Does the age calculator account for leap years?
Yes. It correctly handles leap years (years divisible by 4, except centuries unless divisible by 400) when calculating total days and exact age.
What if I was born on February 29?
The calculator handles leap day births correctly. In non-leap years, your birthday is typically considered March 1 for age calculation purposes.
How accurate is the total days count?
The total days count is exact, accounting for every leap year between your birth date and today. It matches the astronomical day count precisely.
