Start working to move all _( ) gettext calls to a singular file and call the set variable from that list to display the text.  Cleanup date functions slightly, especially in the case of day of week.  Make better use of the validDate setting to tell if the date is valid or not for minutes, hours, day of month, month, and day of week.  Should work for 0 or 1 as Monday, and 7 as sunday.  Used to be 0-6 but the datetime function doesn't represent 0 as a valid parameter, so it sets the day of the week to 1-7 (1 being Monday, 7 being Sunday.
