What is a Leap Year?

A leap year has 366 days instead of 365, with an extra day in February (Feb 29). It keeps our calendars aligned with Earth’s orbit around the sun.

Leap Year Rules

• A year is a leap year if it’s divisible by 4
• But not if it’s divisible by 100 — unless it’s also divisible by 400
• So, 2000 was a leap year, but 1900 wasn’t
