You can add, mark as completed, and delete tasks from the list. A task is a single item that you need to do, often by a specific time. For example, completing a report might be a task that you need to do.
Tasks have many of the same properties as events and are created in nearly the same way.
The difference between Tasks and Events is that Tasks may or may not have a due date associated with it, and although tasks may be viewed, calendar users cannot respond to a task. You can keep track of tasks in the same way that you schedule and manage events, even assigning a due date to your task. You can mark tasks as complete while they still appear on the calendar. They are shown with a line through the task name. In the case of teams working together, members can use the task feature to let others know the task has been completed.
