About this shift calendar
This page helps fast rotating teams calculate day, day, night, night and rest-day blocks. Rotating patterns often move independently of the normal seven-day week, so one reliable cycle date is used to position every future workday and rest day.
WorkPattern calculates the calendar locally in your browser. It can mark public holidays, count shifts and working weekends, estimate hours and pay, check a specific date, and export working dates to popular calendar platforms.
How to get an accurate result
- Confirm the exact sequence. Employers sometimes use different versions of patterns with the same name.
- Choose a reliable anchor date. Use a date you know is day one of the cycle.
- Check the output. Compare several dates with your official rota before exporting.
Calendar export
The downloaded ICS file works with Apple Calendar, Google Calendar, Microsoft Outlook, Samsung Calendar and most other calendar applications. Import it into a separate calendar so the complete rota can be hidden or removed easily.
Accuracy and pay
Results are planning estimates. Confirm crew offsets, shift times, paid breaks, overtime rules, local holidays and payroll treatment with your employer.
