February has 28 days in common years and 29 days in leap years due to the Roman calendar system. Originally, February was the last month of the year, and in an effort to align the calendar with the lunar year, January and February were added. The calendar was further reformed under Julius Caesar, leading to the creation of the Julian calendar, which introduced leap years. The 28-day length was retained for February to maintain the alignment with the seasons, leaving it as the shortest month.
