How to Know if a Year Is a Leap Year
A leap year occurs every 4 years, except for years divisible by 100 unless also divisible by 400. That means:
- ✅ 2024 is a leap year (divisible by 4, not by 100)
- ✅ 2000 is a leap year (divisible by 400)
- ❌ 1900 is not a leap year (divisible by 100 but not 400)
