Check the website for accurate info.
I would think that they would close both parks at 1am... but double check the Disneyland Park app.
Thank you so much but I did call and they are closing at 2 a.m.
I recommend calling. Usually the fastest way to get info
Disneyland closes at 2am on New Year's Eve and California Adventure at 1am, and California Adventure is only open 9am - 9pm on New Year's Day and Disneyland from 9am - 11pm on New Year's Day.
