El año bisiesto

The video explains the concept of a leap year, which occurs 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 seasons, which are crucial for agricultural activities. Leap years have 366 days, allowing those born on February 29 to celebrate their birthdays every four years.
