Some extra relevant information:
A leap year is a year that contains an additional day compared to a regular year. Normally, a year consists of 365 days, but a leap year has 366 days. This extra day, known as a leap day, is added to the month of February. Leap years occur every four years to account for the fact that the Earth’s orbit around the sun takes approximately 365.25 days. By adding an extra day every four years, the calendar is synchronized with the Earth’s rotation around the sun. Leap years are essential to keep our calendar aligned with the natural cycle of seasons. So, if you ever come across a leap year, you can expect it to have 366 days instead of the usual 365.
