Cologne's big events, and how busy they make the city
Every event here is verified by a person, dated from its own organiser, and set against Cologne's day-by-day crowd forecast — so they can be ranked on one scale. "Major" here means an event we have checked and approved as one of Cologne's biggest, whose days our own forecast reads Busy or Packed — or, for now, sit beyond the forecast window.
