The website lists the kitchen's upcoming delivery dates, keeps only the weekdays allowed by the plan's Allowed Start Days, drops dates in the past, and — if Order: Subscription > Subscription Start Date Buffer Period (in weeks) is greater than 0 — also drops any date further ahead than that many weeks. Leave the setting at 0 for no limit (the number of dates shown then follows your general visible-dates setting). If the customer already has a subscription with future deliveries, the new one is offered from after their last scheduled delivery.
