Understanding Leap Years and Calendars

The video discusses leap years, explaining that they exist because the Earth's orbit around the Sun takes about 365.25 days. Without leap years, seasons would shift and calendars would be out of sync. February was chosen for the extra day due to historical calendar structures. The video also covers exceptions to the leap year rule, such as years divisible by 100 not being leap years unless divisible by 400. Finally, it touches on how people might use the extra day on February 29th.
