Tuesdays: an ordinary day of the week with a blocked schedule. Fortunately, Old San Juan feels different. Every first Tuesday of each month, Gallery Night happens. Most art galleries stay open late to show new and permanent collections, while bars and pubs open late to serve the wild crowd.

During the summer, the Company for the Bussiness and Cultural Development for the Isle of San Juan, known as CODEVISA, does not sponsor this event since it works partnered with the Art School of Old San Juan. Still, some art galleries do open late on summers and keep the tradition alive.
