The Cologne Carnival (German: Kölner Karneval) is a carnival that takes place every year in Cologne, Germany.
Traditionally, the "fifth season" (carnival season) is declared open at 11 minutes past 11 on the 11th of the 11th month November. The Carnival spirit is then temporarily suspended during the Advent and Christmas period, and picks up again in earnest after 6 January (Biblical Magi) in the New Year. The time of merrymaking in the streets is officially declared open at downtown square Alter Markt on the Thursday before the beginning of Lent. Street carnival, a week-long street festival, also called "the crazy days", takes place between Fat Thursday (Weiberfastnacht) and Ash Wednesday (Aschermittwoch). The highlight of carnival is Rose Monday (Rosenmontag), two days before Ash Wednesday. All through these days, Cologne folks go out masqueraded. The typical greeting during the festival is Kölle Alaaf!, a Kölsch phrase.
