Its every 15 or 30 minutes during the day. You can also do a self tour. You can't go into the temple though.
Temple Square is open all day for tours,. The Temple itself is open only to church members, but all the other buildings are open to tour
Time changes for Tours, depends on weather.
Los tours del Templo están siempre disponibles
