How the Birthday Countdown Works
Enter your date of birth and the calculator finds the next time that month and day appears on the calendar. It then counts the number of whole calendar days from today to that date.
The birth year is used to show the age you will turn next. It does not change the rarity of your month and day, which is handled separately by the main birthday rarity calculator.
What About February 29 Birthdays?
February 29 only appears in leap years. This countdown treats the next actual February 29 as the next exact calendar birthday. People born on Leap Day often celebrate on February 28 or March 1 in non-leap years, but those are celebration conventions rather than the same calendar date.
