This package contains both a flexible date/time field type Date field and a Date API that other modules can use. This module also facilitates using pop-out calendars for easier recording of various dates/times.
The D5 and D6 versions of the Date field require the Content Construction Kit (CCK) module. The D7 version works with the core Field functionality.
