Arrival You're on a datepicker field. The down arrow will move you into the calendar table, where you can use the arrow keys to select the date, and use enter to make your selection. Press escape to leave the datepicker. If you want to enter the date manually, the preferred format is: Day (in two digits) - Month (in three-letter abbreviation) - Year (in four digits).
