To enable the validation:
Settings→Checkout→Checkout rules (at the bottom of the checkout page)Cart Date Validation rule by DateViewSaveTurn OnProvided the app block is in your cart and visible (ie, not hidden) then the date selected by the customer is validated in checkout; if no date is present checkout will be blocked until a date is selected. This ensures that every order has a date selected.
