Sliding Date-Picker enables you to pick dates with a simple slider bar. By dragging the bar over the time-line, the dates change instantly. Besides this, when the user decides to manually change the dates, the bar is automatically adjusted to the corresponding dates. Sliding Date-Picker is based on Prototype/Scriptaculous, but now combined with the DateJs library as well. It has been tested it in Firefox 2.x and IE6+ and it is licensed under the GPL license.
