Age Calculator
Calculate your exact age in years, months, and days from your date of birth.
How to Use This Tool
- Click the date field and select your date of birth.
- Your exact age in years, months, and days is calculated immediately.
- Additional statistics (total days, weeks, months, and days until your next birthday) appear below.
How It Works
The calculator computes the difference between your date of birth and today's date using JavaScript's Date API. It correctly accounts for leap years, month-length variations, and the current time zone. Days until your next birthday are calculated by finding the next occurrence of your birth month and day.
Frequently Asked Questions
Is my date of birth stored anywhere?
No. The calculation runs entirely in your browser. Your date of birth is not sent to any server.
How does it handle leap year birthdays (February 29)?
If your birthday falls on February 29 and the current year is not a leap year, the next birthday is calculated as March 1 of the following leap year.
Can I calculate the age of someone who has not been born yet?
No. The tool only accepts past dates. Selecting a future date shows an error message.
