It may appear to be a 2-year gap in Europe, since the UEFA (Union of European Football Associations) European Football Championship (referred to as Euro) happens every 4 years, in the even-numbered years between World Cup tournaments. There are other regional tournaments, such as the Asian Cup, run by the Asian Football Confederation, also happening every 4 years. Nevertheless this would never be confused with the World Cup. Such events are scheduled to not conflict with the World Cup, and increasingly with other major regional events. The AFC has decided to change its calendar, moving the Asian Cup to 2007, instead of its original schedule of 2004, 2008, 2012, etc., so as not to conflict with the European Football Championship.
