Built from the posted DSP 12-hour rotating schedule. The rotation is a fixed 28-day Pitman cycle (2 on / 2 off / 3 on, then 2 off / 2 on / 3 off — two weeks on days, then the same pattern on nights), so every C-shift member works these same days. The sheet covers Dec 2025 → Jan 2027; navigation is limited to that range. Shift start/end times are not listed on the schedule.
