# 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.

## 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.
		}
	}
]
