Using the Lightning Calendar Add-on

Lightning is an extension that adds calendar functionality to Thunderbird. You can create your own calendars, subscribe to calendars on the web and manage your own schedule, all within Thunderbird. Lightning also includes a Task manager that allows you to manage an integrated calendar and to-do list.

What is Lightning?

After the Lightning add-on is installed, the interface displays three panels: the calendar overview (on the left), the selected date / duration (in the middle) and the task list (on the right):

You can use this menu to add events and tasks, change the display, and perform various other functions. There also keyboard shortcuts for frequently used actions.

When the Task window is displayed, you can view and manage tasks, including setting the priority, completion status, category, etc. Tasks are associated with calendars; you must selected the desired calendar in the left panel to display the associated tasks.
