Cannes's major events, ranked by crowd impact
Every event here is verified by a person, dated from its own organiser, and measured against Cannes's day-by-day crowd forecast — so they can be ranked on one scale. "Major" here means an event we have checked and approved as one of Cannes's biggest, whose days our own forecast reads Busy or Packed — or, for now, sit beyond the forecast window.
