Google Calendar + Mozillar Sunbird

I found a great way to manage my schedule, mixing Google Calendar and Mozilla Sunbird. Take a look at an easy guideline to find how to do here,

The blogger explains, "First of all, you may be asking, why put Sunbird and Google Calendar together? Well, to put it simply, it offers even more flexibility than what even Sunbird and Google Calendars offer by themselves. To put these two together, we’ll be using Sunbird mainly as our interface and Google Calendar as our “database”, or storage of where the events are actually saved. Note that the only requirement for this is to have an internet connection whenever you wish to access your calendar, but that would not place any new limits if you were using Google Calendar by itself. This combined setup is extremely useful for a number of reasons. If you have more than one computer, such as a desktop and a laptop, and have your Google Calendar configured in Sunbird on both machines, you’ll have completely synced events on both computers without even touching any sort of button with a “Sync” label on it. Another example would be when you are traveling and happen to be away from your computer. You can get on another computer, such as at an internet cafe, and look through your calendar using Google Calendar, where you can edit, add, delete, and do other things with events. When you are finished, and come back home to your computer, those changes made at the internet cafe will automatically update itself in Sunbird, saving you lots of time trying to keep the different copies synchronized."
