Hi Sandra,
Thanks for the great feedback on the additional Google hours!
Holiday hours are part of existing Knowledge Graph fields we sync to Google and other publishers. If your holidays hours are set for dates more than 1 week out, they likely won’t appear on your listings yet. Holiday hours will appear to customers on Google only for the designated days–they are often shown the week of when clicking into the full week’s hours–with formatting designating that these are “special hours.”
More information on holiday hours can be found in this help article or this community post by Liz.
Let us know if you have any further questions!
Thanks,
Jamie
