By its very nature, a Promotion is limited in time and does not necessarily have to be displayed to your customers at all times:
Select the validity dates: in plain English, the booking period to which your promotion will apply
Then select your publication dates: clearly, from when to when this Promotion will be visible on your site and your booking engine
For example, I've created a Promotion "Save 20% on your room" which is only valid from 3 September 2021 to 31 December 2021 in the evening and I only want it to be visible from 10 October 2021 to 31 December 2021 in the evening of the current year.
All that remains is for you to provide additional commercial information that will be published on your website, your booking engine and your booking confirmation documents(vouchers):
