The days on which a product operates are available via the API and should be displayed on your product detail page. If the product supports multiple start times, these should also be viewable by the user on this page. On the viator.com site, days of operation are shown in the availability calendar on the product detail page, and start times and product options are displayed after the user selects a date and passenger mix.Products with a variety of start times that the customer can choose without having to specify at the time of booking will have the available starting times displayed on the voucher.
