1. On the order page click Adjust Delivery Date in the date section.
2. The modal shows the Current date and loads a calendar — Only dates where all selected meals are available on the menu are shown; dates must be after today.
3. Click the new date (it appears under New delivery date) and press Confirm date.

All items, bags and fulfilment details of that date are moved to the new date. The button is available for dates that contain packs, custom meals, by-the-pound or à la carte (Meals by Unit) items and no subscription items. For subscription dates the button is a link that opens the customer's subscription page, where the date is changed instead.
