# Module: Calendar
The `calendar` module is one of the default modules of the MagicMirror.
This module displays events from a public .ical calendar. It can combine multiple calendars.
Note that calendars may not contain any entry before 1st January 1970, otherwise the calendar won't be displayed and the module will crash.

## Using the module

To use this module, add it to the modules array in the `config/config.js` file:
````javascript
modules: [
	{
		module: "calendar",
		position: "top_left",	// This can be any of the regions. Best results in left or right regions.
		config: {
			// The config property is optional.
			// If no config is set, an example calendar is shown.
			// See 'Configuration options' for more information.
		}
	}
]
````
