The video explains that a year is 365.24219 days, not 365, causing a calendar discrepancy. Julius Caesar introduced leap years to correct this by adding an extra day every four years. Without leap years, the calendar would drift from the seasons, causing holidays to shift. The leap year system slightly overcorrects, so adjustments are made every 100 and 400 years to maintain alignment.
