BlockHour: Business Hours Gate

BlockHour is an app that allows ecommerce merchants to block checkout outside of their business hours at the server level, with no bypass option. Merchants can set business hours per day with 30-minute precision, support overnight hours that cross midnight, add holidays to block orders on specific days, and instantly block checkout with the 'Close store now' toggle. Customizable messages can be shown to customers when checkout is blocked. No theme code changes are needed for installation; merchants simply need to set their timezone, hours, and enable the app.
