🔬 Why Not Exactly 4 Weeks Per Month?
Many people assume 1 month = 4 weeks, but this is mathematically incorrect. Here’s why:
If 1 month = 4 weeks exactly:
• 1 year would be 12 months × 4 weeks = 48 weeks
• But 1 year actually has 365.25 ÷ 7 = 52.18 weeks
• This creates a 4.18-week discrepancy!
The accurate conversion:
• 1 month = 4.348214286 weeks (or approximately 4.35 weeks)
• 12 months × 4.348214286 = 52.18 weeks ✓ (matches actual year length)
