Google Calendar is a great, if not the best available tool to share calendars. However, it’s tedious to edit and keep track of it via the web interface. In saving time, integration is your best friend.
Naturally, there is a vast amount of add on’s and tools to sync, integrate and simply work more efficiently with Google Calendar. For example you can sync it with mobile devices like the Blackberry or iPhone using Google Sync. Now you can use Google’s Calendar with Mozilla’s Thunderbird.
For this you will need two Thunderbird add on’s: 
1. Lightning adds a Sunbird type calendar to Thunderbird.
2. Provider for Google Calendar connects Lightning with Google Calendar.
This add-on provides a wonderful service to the Thunderbird application, making integration with the Google Calendar seamless. Make a change on your desktop and it automatically updates Google Calendar, and vis-a-versa. Everything syncs beautifully. For detailed instructions please click here.
