How to use the 2-2-3 Shift Calculator

  1. Enter a cycle start date, hours per work shift and display length.
  2. Review the values before calculating, especially the cycle-day-1 anchor and the shift length used by the real roster.
  3. Select Calculate to map the generic 14-day 2-2-3 work-and-rest cadence and estimate scheduled hours.
  4. Correct the inputs if the result looks unexpected; a common source of error is assuming the generic work/off cadence also defines a day/night rotation.

What this calculator does

Map the generic two-on, two-off, three-on work and rest cadence across a 14-day cycle and estimate scheduled hours from the shift length you enter. Only the values entered on the page are used to map the generic 14-day 2-2-3 work-and-rest cadence and estimate scheduled hours.

Schedule results depend on the cycle start date being aligned with day 1 of the real roster. A one-day error in the anchor date shifts every displayed assignment.

The work/off cadence is Work, Work, Off, Off, Work, Work, Work, Off, Off, Work, Work, Off, Off, Off. Scheduled hours per 14-day cycle = 7 work shifts x hours per shift.

A 2-2-3 pattern needs the correct cycle position

The familiar 2-2-3 rhythm can be implemented with different team assignments and day/night arrangements. This calculator uses a defined repeating pattern; match its cycle start to the real roster before interpreting any generated work or off date.

Calculation example

Example input: Cycle starts on a known first workday, 12 hours per work shift, display 28 days

Example result: 84 scheduled hours per 14-day cycle and two dated cycles in the 28-day output.

Your result will change with a cycle start date, hours per work shift and display length; check the cycle-day-1 anchor and the shift length used by the real roster before comparing it with another system.

How to interpret the result

Named schedules can be implemented differently by employers. Compare the generated pattern with an approved roster before using it for attendance or leave decisions.

In particular, confirm the cycle-day-1 anchor and the shift length used by the real roster and avoid assuming the generic work/off cadence also defines a day/night rotation.

Practical checks before using the result

  • Verify the key assumption: the cycle-day-1 anchor and the shift length used by the real roster.
  • Avoid a common error: assuming the generic work/off cadence also defines a day/night rotation.

Calculation design and testing notes are documented in the Calculator Methodology and Accuracy Policy.
