Introduction to February Length
February Length problems ask whether February has 28 or 29 days in a given year. You must apply leap year rules to determine if the year is a leap year, which affects not only February but also calculations involving dates around February.
Prerequisites
How to Solve February Length Problems
Step 1: Identify the given year
Step 2: Check if the year is divisible by 4
Step 3: If not divisible by 4 → not leap year → February has 28 days
Step 4: If divisible by 4, check if divisible by 100
Step 5: If not divisible by 100 → leap year → February has 29 days
Step 6: If divisible by 100, check if divisible by 400
Step 7: If divisible by 400 → leap year → 29 days; otherwise → 28 days
Example Problem
Example 1: How many days does February 2024 have? Solution: Step 1: Year = 2024 Step 2: 2024 ÷ 4 = 506 → divisible by 4 Step 3: 2024 ÷ 100 = 20.24 → not divisible by 100 Step 4: Therefore, leap year → February has 29 days Answer: 29 days Example 2: How many days does February 2100 have? Solution: Step 1: Year = 2100 Step 2: 2100 ÷ 4 = 525 → divisible by 4 Step 3: 2100 ÷ 100 = 21 → divisible by 100 Step 4: 2100 ÷ 400 = 5.25 → not divisible by 400 Step 5: Therefore, not leap year → February has 28 days Answer: 28 days
Pro Tips & Tricks
- Leap year if: (year % 4 == 0 and year % 100 != 0) or (year % 400 == 0)
- Years 2000, 2400 are leap years (divisible by 400)
- Years 1900, 2100, 2200, 2300 are NOT leap years
- Years 2020, 2024, 2028, 2032 are leap years
- February has 29 days only in leap years
- Leap years occur every 4 years except century years not divisible by 400
