As long as you enter in your postcode before opening the calendar, the day that it can be delivered is accurate according to postage times. We take postage into consideration in both the calendar's booking dates and when preparing the order for dispatch to ensure it is with you on your requested dates.
If the calendar appears grey, this means the style in that size is not available for delivery on these dates. If the calendar is white, this means you can select these dates for delivery.
