International qualifiers will be played across six days between Thursdays and Tuesdays from 2014 to maximise TV coverage and broadcast income, UEFA have announced.
The move will see national teams having just a two-day break between matches in World Cup and European Championship double-headers, in what is being dubbed The Week of Football.
Teams will play either Thursdays and Sundays, Fridays and Mondays, or Saturdays and Tuesdays. Most double-headers are currently being played on Fridays and Tuesdays - leaving the weekends without football.
UEFA general secretary Gianni Infantino told the Leaders in Football conference in London: "You can play every three days - it's what happening in club football all year long so that's not a problem.
"This has been unanimously supported by all 53 national associations.
"If we leave the weekend to other sports then in the medium and long-term it will be damaging."
