It is possible to make predefined holidays and bank holidays visible on your website, so guests can click on them or more easily search for availability, for example, during the Christmas period.
To set this up, go to organisation settings. In the 'Other' menu, you will see a list of different holidays for various countries. Everything you check will become visible on your website.
This also makes the holidays visible in your Planboard, allowing you to easily look up these dates there as well. Don't forget to save the changes before leaving the page.
