Session Opening of the Cologne CarnivalSessionseröffnung des Kölner Karnevals

The Sessionseröffnung marks the start of the Kölner Karneval (Cologne Carnival) season. Every year on 11 November at 11:11, thousands of costumed locals gather in Cologne's Altstadt (Old Town) to officially launch the "fifth season" of Carnival 1. The highlight is the countdown at exactly 11:11 a.m., showering the crowd with confetti and fireworks 2 3, followed by the introduction of the new "Dreigestirn" (Carnival Prince, Farmer, and Virgin) who will symbolically rule the festivities for the coming season. Live performances by famous Kölsche (Cologne) bands entertain the crowd through the day, and after the official events end (around 20:00), the party continues in bars city-wide. Historically, Cologne Carnival revived in 1823 and has been central to the city's identity 4, making the Session Opening a deeply rooted local tradition 1.

Cologne Carnival (Fastelovend) blends pagan pre-Lenten rites and local customs. Participants shout "Kölle Alaaf!" (Cologne above all!) to celebrate community spirit and the temporary suspension of social norms 1. The carnival session, always announced on 11 November, culminates the following spring (Rosenmontag), but the season opening is its official kickoff. The day is lively and secular; attendees of all backgrounds take part in costume, singing and dancing. The established "Dreigestirn" folklore (a costumed trio of Prince, Farmer, Virgin, traditionally a man as the Virgin) has medieval roots and evolved since 1823 to lead the carnival festivities 2.
