When I first came to Germany shops closed at 6.30 pm. That was freedom for me, having come from the UK where shops shut at 5.30 pm with half day closing on Wednesdays, and shut all day Wednesdays, and of course on Sundays and Band Holidays.
However the rest of the opening times, which are still strictly regulated here in Germany were as follows: open from quite early (bakers at 6 am, other food shops maybe 8 am) except for posh clothes shops which may not open till 10 am.
Saturdays: closing at 2.30, except once a month, and in Advent. If a Bank holiday falls on a Saturday or Sunday there is no day off on the Monday, but there are plenty of other days when everything closes (Epiphany, Easter Monday, Corpus Christi, Ascension Day, National holiday (which was on 17 June in those days.) and up to 7 others depending on where you lived.)
Germany still has one of the the shortest and strictest opening hours regulations, but don't go to the Netherlands on Lappendaag. Even the restaurants are shut. This may only apply to Hoorn where we were staying, but other towns may well have similar days.
