The domestic
Disneyland calendar seems to be having issues with events starting after midnight. The Australian/Canadian calendars have both listed a second parade (1:00 am) and third WoC (3:00 am) for quite a while now and it seems consistent with the info that's been coming from Disneyland (e.g., they announced WoC dining packages for a 3:00 am showing, so there will be a 3:00 am showing even if it's missing from the calendar).
I think WDW is doing more to promote the 24-hour day as a special event in and of itself, whereas for DLR it's the kickoff to the 60th anniversary celebration, so the focus is on the 60th and not the 24-hour day per se.
