 Date::Range is a module that provides functionality to query ranges of
 dates. In addition to determining whether a specified range of dates
 includes a given date, it can return the number of days in a range, return
 a list of the dates in a specified range, and determine whether two ranges
 of dates overlap/abut one another.
