Keep the noise down
Good Friday, "Karfreitag," the day of Jesus' crucifixion, is a public holiday in Germany, as is the Monday after Easter Sunday ("Ostermontag"). Don't think you can enjoy the long weekend by hanging out in clubs, though. In 12 of Germany's 16 states, events with loud music are prohibited all day on Good Friday. In three states, loud music is just banned during certain hours.
