There is a way you can sync your Mozilla Thunderbird with your Google Calendar. First what you need is a calendar addon to your Thunderbird email application. There are two major players in this (they are free and open source of course). Mozilla Sunbird and Lighting.

Both of these tools allow you to manage your calendar on your desktop. It’s integrated with Thunderbird so that you can manage your email and calendar in the same location. This is of course the same type of functionality that you get with Microsoft Outlook. Only this is better of course because it is free. But, they only allow you to manage your calendar on your desktop. What happens if you don’t have your computer with you though? What if you are on a trip or on vacation? This is why people love using the free web based calendar from Google. So let’s integrate the two.

Google Calendar Thunderbird Add-on!

This extension simply allows Sunbird and Lightning to read and write events to a Google Calendar. Follow the instructions given on the plugin page to know exactly how to configure the add-on. Here is the link to the extension page where you can download and get instructions for installation.

This article here… http://bfish.xaedalus.net/?p=239 will give you a complete guide to configuring your Thunderbird app to work with any Google Calendar of your choice. This is such a fantastic mashup. Integrating and syncing a desktop calendar with a web based calendar, where both applications constantly talk to each other is priceless. I personally have been looking for something like this for a long time and i’m glad I have come across it. I have already installed this add-on to work with my already running Thunderbird & Lighting. It’s working perfectly for me with not problems at all.
