Date Blocking in Custom Checkout Form

There is no way to change the checkout page. It is a security feature of SS.

Hi, 

I'm a local delivery only bake shop and my customers choose a delivery date during checkout process via custom checkout form. I need a way to block off dates that I am not available to deliver. Has anyone found a good solution to this? 

You can only modify the Product form (before add to cart) Checkout form has been blocked from Squarespace system
