I've found that the online DLR calendar is usually prettty acurate within the 2 week mark, but generally incomplete in the 30 to 45-day mark. Lately the calendar seems more glitchy than normal...possibly because with the new entertainment offerings the old template is not applicable. Hopefully it'll smooth out soon, but for now, the inconsistencies between the dining system, the international calendar, and the domestic calendar are not surprising.
