Visual Calendar Grid Reasoning
Visual Calendar Grid Reasoning problems present a visual representation of a month's calendar grid (like a typical month view showing dates in rows of weeks). You must answer questions about the grid, such as counting how many times a particular weekday appears, identifying the day of a specific date, or determining the first or last day of the month.

Introduction to Visual Calendar Grid Reasoning
Visual Calendar Grid Reasoning problems present a visual representation of a month's calendar grid (like a typical month view showing dates in rows of weeks).

Prerequisites
How to Solve Visual Calendar Grid Reasoning Problems
Step 1: Observe the calendar grid layout (Monday to Sunday or Sunday to Saturday)
Step 2: Identify which weekday appears in the first column (first day of month)
Step 3: Count the number of weeks (rows) in the grid (4, 5, or 6)
Step 4: To count occurrences of a particular weekday, note that each weekday appears at least 4 times, and some appear 5 times
Step 5: A weekday appears 5 times if the month has 31 days and that weekday falls on 1st, 2nd, or 3rd (depending on month length)
Step 6: For 30-day months, weekdays on 1st and 2nd appear 5 times; for 31-day months, weekdays on 1st, 2nd, 3rd appear 5 times
Step 7: Answer the specific question about the grid
Example Problem
Example: In a calendar grid for a 31-day month starting on Wednesday, how many Fridays are there? Solution: Step 1: Month starts on Wednesday Step 2: Dates: 1=Wed, 2=Thu, 3=Fri, 4=Sat, 5=Sun, 6=Mon, 7=Tue, 8=Wed... Step 3: Fridays fall on: 3, 10, 17, 24, 31 (since 31-day month) Step 4: Count = 5 Answer: 5 Fridays
Pro Tips & Tricks
- Dates 1, 8, 15, 22, 29 always fall on same weekday
- Dates 2, 9, 16, 23, 30 fall on same weekday
- Dates 3, 10, 17, 24, 31 fall on same weekday
- A 31-day month has 5 occurrences of weekdays that fall on 1st, 2nd, or 3rd
- A 30-day month has 5 occurrences of weekdays that fall on 1st or 2nd
- A 28 or 29-day month has exactly 4 occurrences of every weekday (except if 29-day, the 29th creates a 5th for that weekday)
