Why does it say "Today is your birthday" sometimes?

When the computed next birthday matches the current date, the calculator displays a special birthday message instead of a countdown.

Does it handle birthdays that already passed this year?

Yes. If your birthday has already occurred this calendar year, the countdown automatically targets next year birthday and shows the correct turning age.

How does it handle leap year birthdays?

If you were born on February 29, the calculator finds the next occurrence of that date. In non-leap years, it may target the next leap year or use March 1 depending on the calculation method.

Does the countdown update in real time?

The countdown is calculated at the moment you enter your birth date. Refresh the page to see an updated countdown with current time values.
