Why Does February Have 28 Days??

The video explains why February has 28 days, tracing back to ancient Rome's calendar system. Initially, the Roman calendar had 10 months, excluding January and February. King Numa Pompilius added these months, making February the last month with 28 days due to superstitions about even numbers. The calendar's misalignment with seasons led to the introduction of a leap month, Mercedonius, which was inconsistently applied. Julius Caesar reformed the calendar using the Egyptian solar calendar, establishing a 365-day year with a leap year every four years to account for the extra 0.24 days in Earth's orbit. This system, with minor adjustments, is still in use today.
