DateCalc

DateCalc is an easy-to-use, timesaving tool for performing date calculations. If you frequently have to flip through a calendar, counting days and hoping you did it right, DateCalc will save you time and prevent errors. You can set options on default number of days, and on whether to treat the start date as day one or day zero. The program was custom designed for home-health nurses and federal employees, and it is a handy tool for anybody who frequently has to do date arithmetic.
