Days Off Calculator
About the calculator

The Days Off Calculator is the world's premier workweek optimization software. It's easily adaptable to construction, maintenance, call centers, assembly lines, retail work, telephone coverage, restaurants, field supervision, dispatching, security, etc.

The calculator helps you schedule work crews over the 7-day week, by working out how many crew members can have any given pair of days off (Saturday/Sunday, Sunday/Monday, etc.) and still fill your personnel requirements. Tell it how many people you need each day, and it tells you how to set up your employees' off-days.

The calculator answers questions like this: My employees work 5 days a week. I need 15 employees to work each day Monday through Thursday, 17 on Friday, 14 on Saturday, and 11 on Sunday. How many employees do I need total? Of that total, how many employees can have Saturday and Sunday off? How many get Sunday and Monday off, and so on for other combinations of days off?

The calculator can generate a variety of reports to make the scheduling process easy.

The calculator is free. There are 3 versions:
  • The Web version runs inside your Web browser. There is no special download required; it simply appears as any other Web page.

  • The Windows version runs on any recent desktop version of Windows. You can download it free.

  • The Mac version runs on Mac OS X 10.1 or later. You can download it free.
The Windows and Mac versions have additional calculation and reporting options not present in the Web version. We suggest that you try the Web version first, and if you find it useful, then download the Windows or Mac version.

The calculator is NOT comprehensive employee-scheduling software. Although the calculator includes extensive reporting features, it is designed specifically to solve days-off problems. The calculator does not figure payroll, track sick leave, schedule vacations, etc. There are many generic employee scheduling programs. Google and Download.com are good sources for locating such software. For an excellent introduction to shift scheduling in general, see 911Dispatch.com, which focuses on call centers, police and fire departments, and the like, but is a very good source of such information for any type of business.
