Is there a better, smaller alternative to the jQuery datepicker? The ui.datepicker.js has app. 70kb which is pretty huge imo. Could it be compressed?
It's not smaller in terms of file size, but arguably "better" is the Any+Time™ DatePicker/TimePicker AJAX Calendar Widget, which is probably the fastest, easiest and most feature-laden date/time picker available. It supports countless formats, custom labels & styles, jQuery UI themes, keyboard accessibility and even time zones! And best of all, it's free under the CC-BY-NC-SA license.
