Where would you be without your online calendar? Your whole life is in there. Unfortunately we are not always in front of our systems when an appointment alarm goes off. That’s why google calendar and its SMS notifications are handy. The calendar is available online so that your family and friends can check your availability. If you work the same way, you can keep your local web calendars synchronized by using one of two tools.

If you use Mozilla Thunderbird and its lightning calendar extension, provided for Google calendar lets you create a new calendar in Lightning / Thunderbird that syncs with an existing google calendar (https://addons.mozilla.org/en-US/thunderbird/addon/4631). Outlook users should try Calgoo Software’s Calgoo apps (http://www.calgoo.com/calgoo_apps/compare.php), which not only allows you to synchronize your outlookand Google calendars and contacts but also gives access to your Google calendar Offline.
