How Does the Birthday Countdown Work?
The calculator uses your month and day of birth to determine the date of your next birthday. It compares that birthday with the current date and time.
If your birthday has already occurred during the current year, the calculator automatically selects your birthday in the following year.
The result is divided into complete calendar months, remaining days, hours, minutes and seconds. The seconds value updates continuously to provide a live countdown.
For people born on February 29, the calculator automatically adjusts the birthday date in years that do not contain February 29.
