Typical
Disneyland schedule, 10 AM to 8 PM during the week (Monday thru Thursday), maybe closing at 9 PM. Weekends are around 9 AM to 11 PM.
DCA hours are a bit more difficult to explain, the typical off-season is usually 10 AM to 6 PM Monday thru Thursday, and 10 AM to 9 PM on the weekend.
But Disney will be hosting a seperate ticketed event at DCA on many days, Mickey's Halloween Treat (MHT).
Here is the list
October 5, 12, 19 and 26 7:30 p.m. to 11:30 p.m.
October 4, 11, 18, 25, 29, 30, and 31 6:30 p.m. to 10:30 p.m.
So that makes DCA's special hours 10 AM to 6 PM on Fridays in October
And then on the other days (October 4, 11, 18, 25, 29, 30, and 31), and the park will be open to the public from 10 AM to 5 PM.
Saturdays in October remain 10 AM to 9 PM (Disney doesn't schedule MHT on Saturdays to allow at least one late night), and 10 AM to 6 PM on the other days that no MHT is scheduled.
