In a leap year, an extra day is added to the month of February. Normally, February has 28 days, but during a leap year, it increases to 29 days.
The reason for this adjustment is related to the Earth’s orbit around the Sun. It takes approximately 365.25 days for the Earth to complete one full orbit. To account for the extra 0.25 days each year, an additional day is added to the calendar every four years. This not only keeps our calendar aligned with the Earth’s position in its orbit but also ensures that seasonal events occur at the same time each year.
