Frequently Asked Questions
How is age calculated exactly?
Age is calculated by comparing your birth date to today's date. The calculator counts complete years first, then remaining months, and finally remaining days, accounting for leap years and different month lengths.
Does the calculator account for leap years?
Yes, our age calculator accurately accounts for leap years when calculating your age, ensuring precise results even if you were born on February 29th.
What if I was born on February 29th?
If you were born on February 29th (leap day), the calculator handles this correctly. In non-leap years, your birthday is typically celebrated on February 28th or March 1st, depending on your preference.
