What it does
The Calendar Widget creates a visual calendar in your sidebar with links to news that was posted on a specific date. For example, if you posted news on February 9th, the calendar would have a link to that article when you click on the 9th.
Please note, this is NOT an Events Calendar widget. This is simply a widget to display alternative ways to link to your News Posts. The events calendars all have their own widgets apart from this default widget.
The only setting for the Calendar Widget is a title for the calendar, which as always, is optional.
