Turn a repeating work-and-rest pattern into a clear calendar. Check any date, find your next day off and estimate average weekly hours.
Use W for a workday and O for a day off, for example WWWWOOOO.
The cycle starts on the date you choose. Each W is a workday and each O is a day off. When the last symbol is reached, the sequence starts again.
Dates before the start date are calculated by repeating the same cycle backward.
The estimate spreads your scheduled work hours evenly across the full rotation. This helps compare patterns with different cycle lengths.
Overtime, paid breaks, training and extra shifts are not included.
A fixed sequence of workdays and days off repeats over time. Choose a cycle start date that you know matches the first day of your pattern, then the calculator maps that sequence onto the calendar.
It is a 14-day pattern: two workdays, two days off, three workdays, two days off, two workdays and three days off. Depending on the workplace, day and night crews may use mirrored versions.
Yes. Select Custom pattern, then enter W for each workday and O for each day off. Spaces, commas and hyphens are ignored.
It creates all-day “Work shift” events for the visible six-week calendar. The file is generated locally and can be imported into common calendar apps.
No. This calculator runs in your browser and does not require an account. The dates you enter are not uploaded by this tool.
Planning estimate only. Your employer’s published roster, shift swaps, leave and workplace rules always take priority over this calendar.
