jQuery Interactive Date Range Picker is a modified version of jQuery UI’s Datepicker. This version is optimized for quickly selecting a date from a list of preset dates/ranges, and they added smooth transitions when additional options are revealed. The modifications include:

• shortcut links to preset date ranges, for example, “Past 30 days” or “Current YTD,”
• links to “All dates before…” and “All dates after…” to simplify selecting a range of values where the data set is very large or the high or low end value is an unknown
• only showing the number of calendars needed for choosing a particular range
