Google My Business Guide
Hours of Operation in Your GMB Profile
Add your regular business hours. Also make sure to use the Special Hours feature that you can prep in advance for holiday hours, or irregular/one-off changes in business hours for team days, events, and so on.
Searches want to be informed with data they can trust, and the most accurate business hours. There is nothing worse, than checking a business’ hours and planning a visit, only to find out it’s closed once you arrive.
Hours For Appointment Only Business
Right now there is no feature available for appointment only businesses. If you don’t run regular hours at your location, or if someone can’t just come visit at a specific set time you will need to leave the hours section blank.
