Frequently Asked Questions
How do I calculate my exact age?
Enter your date of birth and the calculator will compute your exact age in years, months, and days as of today (or any target date you specify).
Can I calculate age at a future date?
Yes! Enter a target date in the optional fields. For example, you can calculate how old you will be on a specific future date.
Why does my age in days differ from years x 365?
Because of leap years. Every 4 years (with some exceptions) adds an extra day. The calculator accounts for all leap years between your birth date and the target date.
What if I was born on February 29?
The calculator handles leap year births correctly. In non-leap years, your birthday is typically celebrated on February 28 or March 1.
