Leap year

The video explains the concept of leap years, which occur every four years to account for the extra quarter day it takes the Earth to orbit the Sun. This adjustment prevents the calendar from falling out of sync with the Earth's orbit, which is crucial for maintaining consistent seasons. Leap years ensure that events like planting and harvesting crops happen at the right time each year. People born on February 29 can celebrate their birthdays only in leap years.
