What are the opening hours for banks, museums and shops?

Working hours in Cuba often start around 8am and end around 5:30pm during the weekdays. Banks are open from 8am-3pm. Museum hours can be very unpredictable, but typically are from Tuesday to Sunday 9am-5pm (with 1/2 days on Sundays and closed on Mondays). If visiting a certain museum is important to you, it would be best to call ahead to confirm it will be opened after your day of scheduled people-to-people activities.
