Understanding Leap Years and Their Impact

The video explains the concept of a leap year, which occurs every four years to align the calendar with Earth's orbit around the sun. This adjustment is necessary because a year is not exactly 365 days but approximately 365.24 days. The extra time accumulates, requiring an additional day every four years, added as February 29. The leap year does not significantly impact daily life but ensures accuracy in astronomical observations and seasonal changes. The video also covers how to calculate a leap year by checking if the year is divisible by 4 or 400.
