Popup Calendar is a calendar and date selector that can be associated with an image next to a form element that requires a date. The calendar pops up, at which point a date can be selected, and it will close the calendar and pass the date down to the input field. It has customizable colors and full year/month navigation. It works on all browsers with Javascript support (Konqueror, IE, Netscape 4, Mozilla, and Opera) and makes choosing dates in forms much more pleasant.
