How to choose the correct start date

Find day one of the complete workplace cycle, not simply the first shift in the current week. A six-, eight-, nine-, fourteen- or twenty-eight-day rotation moves independently of Monday-to-Sunday weeks. Starting on the wrong phase creates a calendar that looks plausible but assigns future duty days incorrectly.

When to use a custom rotation

Use the custom builder when the workplace swaps day and night teams on a different interval, inserts relief days, uses a local Kelly variation or combines unequal blocks. Enter every workday and rest day in one complete cycle, then repeat the whole period.

Turn the schedule into a pay estimate

Add actual start and end times, unpaid breaks, overtime settings and shift allowances. The monthly summary totals hours and estimated gross pay. Export the resulting calendar as CSV or ICS after reviewing the dates.
