Ammon News - 2024 is a leap year, meaning Thursday, Feb. 29 is a once-in-every-four-year event.

Since leap years typically happen every four years (although there are some exceptions), our last leap days were in 2020 and 2016, and the next leap year will happen in 2028.

What is leap day?
Leap day is an extra day that gets added to the calendar. During a leap year, which occurs every four years, leap day falls on Feb. 29, giving the shortest month of the year one added day.

Why is leap day every four years?
The reason there are leap days, and years, is because of the Earth's orbit.

The amount of days it takes for the Earth to complete a full revolution around the Sun is not a whole number. The 365 days we experience is actually 365.242190 days, according to the National Air and Space Museum.

That fraction allows seasons to correctly line up each year. If leap day was left off the calendar, the months during which we normally experience each season would eventually shift. This would impact other aspects of life, such as the growing and harvesting of crops.

When added, four 0.242190 days roughly equal one full day, which is why Feb. 29 is added to the calendar of most years that are divisible by four, including 2024.

Upcoming leap days
This year, 2024, is a leap year. Leap day will fall on Thursday, Feb. 29.

The next leap years will be in 2028, 2032 and 2036.
