There Were 52 Mondays in 2024

2024 had exactly 52 Mondays, matching its 52-week span. Since January 1, 2024, was a Monday, the year started and ended on the same day, ensuring no extra week. Leap years (like 2024) can occasionally add a 53rd Monday if they begin on a Sunday.

How to Calculate Mondays in a Year

  • Step 1: Identify the weekday of January 1 (e.g., 2024 started on a Monday).
  • Step 2: Count 52 Mondays (one per week) as a baseline.
  • Step 3: Check if the year has 52 weeks + 1 extra day (like 2024). If that day is a Monday, add 1 more (not applicable here).
  • Step 4: Leap years add a 366th day-if it falls on a Monday, a 53rd Monday occurs (e.g., 2020).
