Used Count Days for Windows?
Editors’ Review
This application can accurately count the total number of days between two dates, yet user-specified changes are limited.
Although it won't win any design awards, Count Days has a basic and straightforward interface that any user can easily grasp, even without a help file. Upon providing the start and end dates to calculate, the program immediately computes the total number of days, working days, weeks, months, and years between them.
However, it would be nice if Count Days had an option for users to input their own actual working days, or a way to calculate the working days with consideration to fixed holidays.
Any user looking for a no-nonsense, clear-cut, and free application that lives up to its name surely can settle for this one.
