In CP, there is the widget called "Recent Entries". You can pull out entries from your sections, limit a count of entries.
I'm building a plugin that has very similar widget to recent entries widget.
Filter entries by date range within widget.
I was only able to set a fixed date range within widget's class ...
// To get entries from a specific date range $criteria->postDate = array('and', '> 2016-06-10 23:59:59', '< 2016-06-30 00:00:00');
