📅 Leap Years – Explained Simply
A leap year is a year that has 366 days instead of the usual 365. The extra day is added to the month of February, making it 29 days long instead of 28.
✅ Why Do We Have Leap Years?
Because the Earth takes about 365.25 days to orbit the Sun. That extra 0.25 day each year adds up, so every 4 years we add 1 extra day (0.25 × 4 = 1 day) to keep our calendar in sync with Earth’s orbit.
