🧠 What Is a Leap Year?

A leap year is a year that has 366 days instead of the usual 365 days. The extra day, February 29, is added to keep the calendar synchronized with the Earth’s rotation around the Sun.

According to the Gregorian calendar, a year is a leap year if:

The year is divisible by 4, and

If the year is divisible by 100, it must also be divisible by 400

🧾 Leap Year Rule Examples

2000 → Leap year (divisible by 400)

1900 → Not a leap year (divisible by 100 but not 400)

2024 → Leap year (divisible by 4)
