In a shift-work metro, the hours table is the most read block on the site
When a large part of the workforce keeps unusual hours, availability is not a footer detail, it is the offer.
Most dental sites bury hours at the bottom of a contact page in small type, sometimes as an image. Meanwhile the single most common reason a visitor leaves is that they could not work out whether they could ever get there.
Put hours near the top, as text, per location, with the early and late blocks called out explicitly. If you open at seven on Tuesdays, that is a headline in a metro built around freight shifts, not a line item.
Say what happens outside those hours too. A visitor at eleven at night wants to know when a human answers and whether anything can be done before then. Silence reads as closed indefinitely.
Keep it honest and keep it current. Hours that disagree with your Google Business Profile create calls at locked doors, and those patients rarely try twice.
