Selecting  Options    Calendar  brings up a form where you may adjust several calendar settings (partly general, partly concerning only the calendar from where you called the form). The calendar settings include the following:

• Appointments are displayed in different colours indicating their category or recent events.
• Appointments in a group calendar to which you are invited are automatically entered into your personal calendar.
• Appointments that you create in a group calendar are automatically entered into your personal calendar (also if you do not participate!).
• Appointments where you do no longer participate are automatically removed from your personal calendar.

Additionally, you may specify your personal preferences for the arrangement in the calendar views: first day of the week, working days in a week, and time scale in day and week views.
