Unless something requires him to close by the city or county Yep they're open except for on Christmas
Yes
Unless there's a pandemic lockdown, MBA is open every day but Christmas!
If you are in Monterey I would stop by the aquarium and ask one of the staff that are located in front of the entrance.
According to the web site the Aquarium will be open July 4th. The usual hrs 9AM to 6pm might be modified. I would call Monday to get the actual hrs.
