Enter the day you land. Museum Island closes on Mondays, shops close on Sundays, the free Philharmonie concert is a Wednesday, and Sanssouci Palace in Potsdam skips Mondays. The board puts each day where it works.
Opening days checked on 13 October 2026 on the official pages of the State Museums, the Prussian Palaces Foundation, the Bundestag, the Berlin Wall Foundation, the Sachsenhausen Memorial and the Berliner Philharmoniker. Sunset is calculated for central Berlin. Holiday weeks around 24 December to 1 January have their own hours, so check each venue then.
