As skiingfast and HydroGuy indicated, DLR seems to roll its calendar out in stages. The September calendar just became finalized last week, I think it was. The full, complete, finalized October Calendar will appear sometime in September, but little bits of it will pop up here and there - and then they may suddenly vanish and reappear again - before then. DLR has been known to put certain things on the calendar and then remove them and then put them back again before the whole process is finished!
Never fear! There will be World of Color (probably once per night) and Saturday-Sunday fireworks (Tuesday and Friday fireworks, as well as fireworks on October 3rd and October 31st, will be reserved for the Halloween party guests)!
