Time Shift Rotation
Time Shift Rotation puzzles involve scheduling people across multiple days with rotating shifts. Each person works one shift per day, and shifts rotate forward by a fixed number of positions each day. These puzzles test your ability to track temporal patterns and predict future assignments.

Introduction to Time Shift Rotation
Time Shift Rotation puzzles involve scheduling people across multiple days with rotating shifts. Each person works one shift per day, and shifts rotate forward by a fixed number of positions each day. These puzzles test your ability to track temporal patterns and predict future assignments.
Prerequisites
How to Solve Time Shift Rotation Problems
Step 1: Identify the number of people, shifts, and days
Step 2: Note the initial shift assignments for each person on day 1
Step 3: Understand the rotation rule (e.g., each person's shift advances by 1 position each day)
Step 4: For a given person and day, calculate: shift = initial_shift + (day_offset × rotation_step) mod total_shifts
Step 5: Track the schedule using a table: days as columns, persons as rows
Step 6: Answer the specific question about who works which shift on which day
Example Problem
Example: Five guards work rotating shifts (Morning, Afternoon, Evening, Night, Graveyard). On Monday: A=Morning, B=Afternoon, C=Evening, D=Night, E=Graveyard. Each person's shift advances by one position each day. What shift does C work on Wednesday? Solution: Step 1: Monday: C=Evening Step 2: Tuesday: C=Night (advance one) Step 3: Wednesday: C=Graveyard (advance one) Answer: Graveyard
Pro Tips & Tricks
- Rotation step is usually +1 position per day
- After total_shifts days, each person returns to their original shift
- Shift sequence is cyclic: shift₁ → shift₂ → ... → shiftₙ → shift₁
- Use modular arithmetic: shift_index = (initial_index + days_passed) mod total_shifts
- Create a shift order list for reference
- Track one person's schedule to verify the pattern
