Question 1

How is age calculated?

Accepted Answer

Your age is the number of complete years between your date of birth and today. The day and month must have passed this year for the year to count, which is how official (international) age works.

Question 2

What is the difference between exact age and age in years?

Accepted Answer

Age in years is the big number shown first. Exact age breaks it down further into years, months, and days for a precise result.

Question 3

How is the next birthday countdown calculated?

Accepted Answer

It counts the days from today until your next birthday. If today is your birthday, it shows a celebration message instead.

Question 4

How are leap years handled?

Accepted Answer

Leap years are counted automatically. If you were born on February 29, your birthday is shown on March 1 in non-leap years.

Question 5

Is my date of birth sent to a server?

Accepted Answer

No, all calculations happen entirely in your browser. Your date of birth is never uploaded or stored anywhere.
