New Year’s Eve (Sylvestr) in Prague is one of the most festive holidays of the year for the Czechs.  Central Prague is a big party especially on Wenceslaus Square where music and dancing go on all night.  At midnight go near the river where the fireworks light up the sky to ring in the new year.  This year it might be a little quieter due to the restrictions so do be aware of this when you plan your evening.
