Bs_DatePicker Widget
The DatePicker lets users easily select valid dates. No need to worry about date formats, by picking dates it's always correct. See the website for screenshots and examples. Browsing through the years is possible. No unix-like date limit (works with pre-1970 dates). Choose from us, european or iso-date format. Customize the look and feel. Can be used with time too. Multilingual (currently en/de/fr, create your own lang file). Supports skins. Allowed date ranges can be allowed. Lots of settings and API methods.
