The calendar provides different views (year, months, week, day) conforming with the usual "look-and-feel" of calendars. Users may enter appointments directly into the calendar. In addition to the personal calendar of each user, calendars can be created within folders and may then be used as a joint calendar for a group of users (group calendar).

The calendar functions support you in planning, preparing and documenting an appointment for a group of invited participants -- be it a traditional face-to-face meeting or a virtual meeting using a computer conferencing program. Selection of participants is not limited to the members of the workspace in which you create the appointment.

For details about the calendar object see section 5.1.
