We are Orthodox, Sabbath-observant Jews, and we need a way to disable the checkout system on our Shopify store for every Sabbath (from Friday evening, 18 minutes before sundown in the New York area, until Saturday night, 1 hour after sundown) and for specific Jewish holidays. The site can remain browsable, and customers should still be able to add items to their shopping cart, but checkout should be disabled during these times. I would like the system to be as automated as possible, and to not require access to external servers. I had another developer create an app like this several years ago for another Shopify site we run, but he designed it in a way that required access to his server. Now I can no longer reach him and the app has stopped working. So I'd like to avoid that.
