What Is a Leap Year Birthday?
A leap year birthday usually refers to someone born on February 29. Since Feb 29 only appears in leap years, many people celebrate on Feb 28 or Mar 1 when it’s not a leap year.
How This Leap Year Birthday Tool Works
Step 1 – Check if your date is Feb 29
If your birth date isn’t February 29, the tool shows: “You are not a leap year baby.”
Step 2 – Find the next official Feb 29 birthday
We scan forward to the next year that contains February 29 and show that date as your next “official” leap-day birthday.
Step 3 – Choose a celebration date in non-leap years
You can choose whether you celebrate on Feb 28 or Mar 1 when the year is not a leap year. The tool then shows your next celebrated birthday date accordingly.
