At that time there was not a unified state of "Germany". It was a more or less loose union called the "Holy Roman Empire of the German Nation". The region I live in switched on 16/27 Nov 1583. But I prefer a unified rule, so my programs use the "official" date, i.e. 4/15 Oct 1582.

I'm not sure which edit you refer to, but I think the following link provides a nice and comprehensive overview for the European states:
The adoption of the Gregorian calendar.

You can see that also France did not switch on one single date. At that time some French regions like Strasbourg or Alsace were part of the Holy Roman Empire. Which in turn shows how closely French and German history have been related over the centuries (think of Charlemagne / Karl der Große).
