When is the Next Leap Year?

Leap years are most important for a year that occur almost every four years, adding an extra day to our calendar. For this adjustment our calendar is in sync with the Earth’s orbit around the Sun, which takes approximately 365.25 days.

Understanding Leap Years

The concept of leap years has been used since ancient times, and has been refined over the centuries to conform to the rules of the current Gregorian calendar. Without leap years, the calendar would gradually drift, causing seasonal events and astronomical observations to occur on different dates over time.

Leap Year Rules Revisited:

• A leap year is a year if it is evenly divisible by 4.
• However, if the year is evenly divisible by 100, it is not a leap year, unless...
• Even if the year is evenly divisible by 400. In that specific case, it is a leap year.

Generally speaking, the year 2000 was a leap year (divisible by 400), but 1900 was not (divisible by 100 but not 400). The year in the next century that will be a leap year is 2400.

Why Do We Need Leap Years?

The period of Earth's orbit in a tropical year is about 365.2422 days. Our daily calendar uses 365 days. The remaining 0.2422 days accumulate and, after about four years, they add up to about a full day. Adding February 29th corrects this discrepancy, which keeps the calendar from falling behind the astronomical year.
