# Groupware Calendar Settings

Groupware Calendar Settings refer to the administrative configuration of individual calendars within the [[groupware]] platform. The Groupware calendar allows users to manage their schedules and share them with others using a granular permission system based on **Calendar Access Control Lists (ACL)** to determine who can view or modify calendar data.

## Configuration Process
To modify calendar properties:
1. Open the **Calendar module** in [[groupware]].
2. Click the **gear icon** in the horizontal bar.
3. From the resulting list of manageable calendars, **double-click** a specific calendar to open its properties.

## Calendar Permissions
Permissions are managed under the **Berechtigungen** (Permissions) tab. Rights can be assigned to either individual users or predefined groups.

### Permission Levels
| Level | Description |
|-------|-------------|
| **Read-only (Nur Lesen)** | The default setting; allows viewing of entries/the calendar without modification. |
| **Write (Schreiben)** | Allows the user/others to create and edit calendar entries. |
| **Administrative (Verwalten)** | Grants full control over calendar settings and permissions / the ability to manage the calendar's overall settings. |

**Warning:** Administrative rights provide significant control over the calendar; users should exercise caution when granting this level of access.

## Group Visibility and Management
When permissions are granted to a group, the system provides an icon (located to the right of the group permission entry) that allows the administrator/user to verify exactly which users are members of that group.

## Support
For issues regarding calendar configuration and technical settings, users are directed to the [[universitatsrechenzentrum-urz]] via:
- The [[groupware]] ticket system.
- The URZ hotline at extension **1420**.
