Calendar:Creating new calendars
In Sunbird and Thunderbird with Lightning it's possible to have multiple calendars. You can create these in calendar-mode or in task-mode by rightclicking in the calendar-list (choose "New Calendar") or by choosing File"-"New"-"Calendar".
Next you get to choose wether you want to create the calendar "on your computer" or "on the network".
On your computer - local calendars
When choosing on your computer you can only use the calendar on the computer you're working at. All the data is stored inside an internal database (the sqlite-file storage.sdb in your thunderbird-profile). Next you get to choose which name and color your calendar should have and your calendar is ready to use.
On the Network
When choosing "On the Network" your files can reside on general webservers (readonly), on webdav-servers, on specialized caldav or wcap-servers, on the local filesystem or a network-share, on ftp-servers or you could use your google-calendars.
You're able to subscribe to calendars provided by third parties, mostly in ics-format. These are almost always read-only, you're not able to change anything for the calendars. An example of this kind of calendar are the holiday-calendars provided by mozilla. Choose ics and enter the url in the Location Field. Next you can choose the name and color for the calendar you just added.
Select the "Format" - "Sun Java System Calendar Server (WCAP)
Enter the http: URL for you WCAP server.
Enter a "Name"
(Optional) Select a "Color".
