About Group Calendar:
Group Calendar allows guilds or groups of friends to share an in-game event calendar. The guild can post raid events and members can post events for dungeons they need to do quests for. Additionally, players can provide feedback to the event's sponsor saying that they will or won't be attending an event. Once installed Group Calendar replaces the minimap current time tooltip and sun & moon icon. This can be used to open the UI or it can be opened using the /calendar command. For instructions on how to set up Group Calendar for your guild or for your personal use, see the online user's manual
