Most shops, especially grocery shops, markets, small souvenir shops, and stalls are open daily. Grocery shops are open usually from 7 am - 9 pm, other smaller shops sometimes take a break around noon. During the summer, galleries and museums are usually open from 9 am to 8 pm. Some operate daily, while others close once a week, often Monday, Tuesday, or Wednesday. If you plan to visit a few museums/attractions, it may be worth buying a Dubrovnik Pass, which also includes entry to the city walls.
