The "Boeoegg" burns on the Sechselaeuten square in Zurich, Switzerland, on Monday April 17, 2023. The Sechselaeuten (ringing of the six o'clock bells) is a traditional end of winter festival with a parade of guilds in historical uniforms on horseback and the burning of the Boeoegg, a symbolic snowman, at 6 pm. The faster the Boeoegg explodes, the hotter the summer will be according to traditional weather rules. (KEYSTONE/Michael Buholzer)
