This BITS object sets the ending day or days of the week on which a periodic entry's referenced configuration is no longer in effect, combined with timeRangePeriodicEndTime to form the full end day-and-time; the same day(s) set here must match timeRangePeriodicStartDay when multiple days are specified. An admin uses this to define exactly which weekday(s) a recurring schedule window closes on. For example, matching the start day example, an admin would also set the monday(2) and friday(6) bits here to mark those as the days the schedule window ends.
