Know The Secrets of  Leap Year

Arrow

Earth takes around 365.25 days to go once around the Sun. That's a bit more than our regular calendar year of 365 days. To fix this, we add an extra day to our calendar every four years.

Earth's Orbit

Arrow

The additional 0.25 days accumulate over four years, totaling around one extra day.

Extra Time

Arrow

To account for this, a leap day is added to the calendar every four years.

Leap Day Addition

Arrow

The actual time for Earth to complete its orbit (sidereal year) is about 365 days, 5 hours, 48 minutes, and 56 seconds.

Sidereal Year

Arrow

Without leap years, our calendar would gradually misalign with the seasons.

Seasonal Drift

Arrow

While most leap years occur every four years, exceptions exist. Years divisible by 100 but not by 400 skip the leap year.

Leap Year Rule

Arrow

Adding a leap day every four years doesn't precisely match Earth's orbit, causing a 23.26-hour difference. This makes our calendar longer by over 44 minutes.
