Government office hours are from 8:30am to 12:30pm and 1:30pm to 5:30pm, Monday through Thursday. Working hours on Friday are 8:30am to 11:30am and 1:30pm to 5:30pm. Private businesses are often open on Saturdays.
Museums and other historical sites generally keep similar hours, but also open on Saturdays and Sundays (Perhaps slightly shortened hours). National Park and other natural sites of interest are typically open to day visitors from around sunrise to sunset (say 06.00 to 18.00). However, most churches of interest to tourist have no fixed opening hours beyond mass times, and may close almost anytime at the whim of the priest.
