X-office suits

Plan displays a month calendar similar to xcal, except that every day box is large enough to show appointments (in small print). Appointments can be associated with the following information: date, time and length (in time or days); an optional text message to be printed; an optional script to be executed; early-warn and late-warn triggers that precede the alarm time; repetitions (every nth day, etc.); optional fast command-line appointment entry; flexible ways to specify holidays and vacations; extensive context help; multiuser capability using an IP server program (plan-server with access lists); and grouping of appointments into files, per-user, private and others. Plan can be connected (with additional software) to Apple Newton and PalmPilot PDAs. You'll need either Motif or LessTif in order to use Plan.
