It is common knowledge that Germany has a law which prohibits dancing and loud music at certain religious holidays, such as Good Friday. The month with the most dance-ban days every year is November (the four days ahead of Easter are also days on which dancing is banned). Catholic Bavaria is even more liberal in that point than some other German states. For example, this Saturday (October 31) is Halloween and you can party until 2am in Bavaria, but only until 12am in Baden-Wurttemberg, because November 1 is catholic All Saints’ Day. Alles klar?
That doesn’t mean that the clubs and bars will close at that time, but the music will be turned down and there’ll be no dancing, unless you want to live wild and do something illegal. Other dance-ban days in November include Volkstrauertag (November 15), Day of Prayer and Repentance (Buß- und Bettag, November 18) and Totensonntag (November 22).
