Leap Year Rules
The Gregorian calendar uses three rules to determine leap years:
- If the year is divisible by 4, it might be a leap year.
- If the year is also divisible by 100, it is not a leap year.
- If the year is also divisible by 400, it is a leap year.
Examples: 2024 (leap), 1900 (not leap), 2000 (leap), 2025 (not leap).
