How often is leap year?
A leap year occurs once every four years. It is a year that has an extra day, February 29th, to keep our calendar in alignment with the Earth’s revolutions around the sun. This additional day is added to help account for the slight discrepancy between the length of a solar year (about 365.25 days) and our traditional calendar year (365 days).
To be more specific, leap years follow a specific rule. A year is considered a leap year if it is evenly divisible by 4. However, if a year is divisible by 100, it is not a leap year, unless it is also divisible by 400. This rule helps maintain the accuracy of our calendar system and prevents the accumulation of time discrepancies over centuries.
For example, the year 2020 was a leap year because it is divisible by 4. However, the year 1900 was not a leap year because although it is divisible by 4, it is also divisible by 100 and not divisible by 400.
Overall, leap years occur approximately once every four years, with some exceptions to maintain the accuracy of our calendar system.
