The International Rugby Board have confirmed the 2015 Rugby World Cup in England will kick off on September 18.
The decision was approved at the annual meeting of the IRB Council in Dublin following an exhaustive review process which resulted in the date being recommended by chairmen and chief executives of the 10 tier one nations.
It means tournament owners Rugby World Cup Limited (RWCL), organisers England Rugby 2015 Limited (ER 2015) and the unions can now step up their preparations for what is expected to be the biggest tournament so far.
IRB and RWCL chairman Bernard Lapasset said: "Throughout this collaborative process we have set out to achieve a Rugby World Cup start date that is good for participating unions, good for our other major international rugby events and ultimately good for the development of the global game.
"September 18 achieves just that and coupled with a new and robust collaborative funding model, we have collectively moved to address the challenges that face our unions during a Rugby World Cup year."
