We went to Disneyland in early October and the hours were I think from 9 or 10 and I know for sure they closed at 8. Friday they were open from 9 until 10, and Saturday until midnight. California Adventure was from 10 until 6, and open until about 8 on Friday. They only do the Electric Light Parade on Fri-Sun though. It was a good time of year to go because it was not crowded and we could still wear shorts.
