The opening hours information is specifically designated for the "LocalBusiness" type. How can I include office hours in the Rich Results?
You’ll need to use the “LocalBusiness” schema type instead of “Organization” to include your office hours in the Rich Results. The “openingHoursSpecification” property is specifically designed for the “LocalBusiness” type, which represents a physical business location.
By switching to the “LocalBusiness” schema type and correctly implementing the “openingHoursSpecification” property, your website will be validated by schema.org and have a higher chance of displaying the desired rich results in Google Search.
