May; the last month before exams is the last bout of freedom for the students in Krakow. Juvenalia is a holiday for students and takes place every year for a week in May. Across the city, on all five campuses, you can hear music from concerts, and smell the odor of hamburgers on the grill.
The festival culminates with the symbolic passing of the key to the city by the mayor to the students of Krakow. This, in turn, gives the students the freedom to break the law by means of drinking in public places. And helps them raise their voices in song as they chant their alma matters hymns in the main square. Be careful when going into the square today as you can be accosted by young adults dressed in various costumes, intoxicated since the sun rose, screaming slogans in a language you may not know.
