उत्तर २
A leap year is a year that contains an extra day, February 29, making it 366 days long instead of the usual 365. This adjustment occurs approximately every four years to keep our calendar in alignment with earth’s orbit around the sun. Without leap years, our calendar would gradually drift out of sync with the seasons.
