The UEFA European Football Championship, less formally the European Championship and informally the Euros, is the primary association football tournament organized by the Union of European Football Associations (UEFA). The competition is contested by UEFA members’ senior men's national teams, determining the continental champion of Europe. The competition has been held every four years since 1960, except for 2020, when it was postponed until 2021 due to the COVID-19 pandemic in Europe, but kept the name Euro 2020. Scheduled to be in the even-numbered year between FIFA World Cup tournaments, it was originally called the European Nations' Cup, changing to the current name in 1968. The individual events are branded in the form of "UEFA Euro [year]".
