We have leap year (an extra day is added to the calendar year) every 4 years to keep the calendar year in sync with the solar year (how the earth revolves around the sun, which is how the seasons go). The earth does not revolve around the sun in an exact whole number of days.

But even that gets off after awhile, so every 100 years we have to eliminate leap day to make up the difference, and every 400 years we bring it back to prevent overshoot.

Leap seconds are also added every once in awhile to keep the clocks in sync with the rotation of the earth on its axis. Many people never even know that these occur, though.

Is every 400 years a leap year?

All years divisible by 4 are leap years. Exceptions occur at the end of century: if the year is divisible by 100, it is not a leap year, unless it is also divisible by 400. Thus, 1700, 1800, 1900 were not leap years, but 1600 and 2000 were leap years.All years divisible by 4 are leap years.

What factor is used to determine a century leap-year?

Only century years divisible by 400 qualify to be a leap year. Years divisible by 4 but by 100 are NOT leap years, thus 1700, 1800, and 1900 were not leap years but 2000 was. 2100, 2200 and 2300 will not be leap years but 2400 will be.

Future leap years?

Leap Years are years divisible by four, with two exceptions. 1. "Century" year numbers (divisible evenly by 100) are not leap years. 2. Years divisible evenly by 400 ARE leap years. So years like 1992 and 1996 were leap years. Century years like 1900 or 2100 are NOT leap years. But 2000 was a leap year, and 2400 will be.
