A simple color-coded desktop calendar for 24-hour rotating shifts. Useful to Fire Service employees, family and friends. Can optionally be activated from system tray.Simple setup, simple functionality but free. No ads, does not need to connect to internet with the exception of Online Help which is really not needed. The limitation of this program is that it does no printing and does not create web calendars. This program installs with Window Installer and will leave a few settings in the registry when uninstalled. The settings are retained simply to save your schedule setup for the next install.
