Great Calculator 5 out of 5.0
User: , Correctional Case Records Supervisor of California Dept. Corrections and Rehabilitation from Imperial, CA.
User Rating: ★★★★★
I have worked Corrections for over 20 years and have seen calculators come and go. The ScheduleCalc beats all the others hands down. We use this calculator daily to complete our work. It is a necessity in the date calculations of inmates. Cost comparison, it is the least expensive of all that I have experienced over the years and with the least maintenance needed. However, when the buttons wear out, as ours have then we have to have them replaced.

Good Functionality 4 out of 5.0
User: of Commercial Diver from Miami
User Rating: ★★★★
A schedule calculator that is absent a clock and day/date function is less than thoughtful.
