Date Component


Function: a!dateField()

Displays and allows entry of a single date (year, month, day). When the field is editable, users can input dates by typing or by picking from a calendar.

When working with date and time (year, month, day, hour, minute, second), use a date & time component. To display a time (hour, minute, second), use a time component. To display a read-only date using a custom format, use a text component.
