Why February has 29 days in a Leap Year

Introduction of the Solar Calendar00:00:00

Julius Caesar introduced the solar calendar, consisting of 365 days, which moved January and February to the beginning of the year and adjusted month lengths.

The Origin of the Leap Day00:00:31

To account for the extra six hours accumulated each year, one day is added every four years to compensate for the drift in the calendar.

Why February?00:00:40

Because February was already the shortest month of the year, it was selected to host the additional day during a leap year, resulting in 29 days.
