wmCalendar is a calendar dockapp with a monthly view and an interface to iCal-based calendars like Evolution or Mozilla. It features Gregorian, Persian, and Islamic calendar support, moon phases, variable start of the week, popup detail info about a day's events, and app.launcher.
wmwork provides a monitor on a 64x64 mini window that helps you keeping track of your time. The idea is based on the Worklog program. In contrast to Worklog, wmwork is a graphical application designed to work with the Window Maker dock, but will also work with other window managers.
