Video transcript

February has 28 days because of its historical roots in the Roman calendar. Initially, the Roman calendar had only ten months, and winter was a monthless period. When January and February were added, February was assigned 28 days to make the calendar align with the lunar year. Later reforms, including the Julian and Gregorian calendars, kept February shorter to balance leap years, ultimately preserving the 28-day tradition.
