If you run a promotion that gives a discount only if a booking is made for a specific day of the week - for example, a promotion that gives discount only if customers make a booking for a Friday, you should follow the steps below.
1. Go to Marketing>Promotions
3. In the Days and Times of the week section, select the start time of the booking must be within one of the following intervals, and set the start times and days when the promotion is applicable. In our example, the promotion is only valid on Fridays, so the screenshot below shows that the promotion is valid for bookings made for Fridays, with a start time between 9am to 6pm.
