If you have installed Baikal (see article Baikal with Nginx and https ) you can start to synchronize its data.
Sync Calendar Data with Lightning
Lightning is an add-on for Mozilla Thunderbird and expands the e-mail application with a calendar and scheduling tool. More information about Lightning can be found on the page from Mozilla: Using the Lightning Calendar Add-on.
If you want to have your calendar- and contact-data synchronized and don't want to give it away to third parties, it is possible with very simple means to synchronize it at home on your own server. The flagship in this direction is OwnCloud, which also provides CalDAV and CardDAV for synchronization. However, I had always had problems with the synchronization, and so I wanted to give Baikal a try.
Baikal is a PHP written, small and robust server to synchronize calendar and contact data using CalDAV and CardDAV.
Now that I finally had my little server, I wanted to sync all my stuff from a variety of electronic devices: ie the working files on different computers, and also the calendar data and addresses should finally be in sync on all devices.
After a quick search I am first came to OwnCloud. A truly worry-free solution and also really easy to install.
