Jquery is my all-around favorite Javascript library for developing websites with rich UIs (among many other assorted goodies offered by Jquery). In this post, I share my favorite date and time picker Jquery plugins.
Not strictly speaking a plugin, Datepicker comes out of the box as part of the Jquery UI add-on library, and is a tried and true rich UI date picking widget, with lots of config options. If you need something that “just works” quickly and gets the basic (date picking) job done fast, look no further than this one.
