iCalendar is a format used to exchange data which allows compatibility with various calendar type applications such as Google Calendar, Microsoft Outlook, Microsoft Exchange, Apple’s iCal and Lotus Notes, just to name a few.
Events are stored online, so in the case of a user’s hard drive failure, no data is lost.
The below screenshots are taken from an example Google Calendar. Google Calendar is a contact and time management web application offered by Google. The interface is similar to desktop calendar applications such as Microsoft Outlook. Users can view, add and even drag-and-drop events from one date to another without reloading the page. It supports a variety of view modes, such as weekly, monthly and agenda views.
Multiple calendars can be added and shared, allowing various levels of permissions for the users. This enables collaboration and sharing of schedules between groups of people across multiple locations.
