Display of the expected delivery date

In the product detail view, the delivery status appears in detail with this module:

"Estimated delivery date within Germany:
Friday 20 May 2016 - Monday 23 May 2016".

The calculation is made by specifying the calculation basis (day, week, month) in the delivery status and - if available - separators ("Delivery time: 3-4 days").
The module also takes Sundays and optionally Saturdays into account. It also takes into account public / floating holidays and the time up to which same-day delivery should be possible.

Note for Modified 2, this module is only partially updateable.
