Wales' Six Nations opener with England will be the last Friday night fixture for the foreseeable future.
Championship chief executive John Feehan has confirmed the Six Nations experiment, run for the last two years, will be scrapped for 2012 and 2013.
The Six Nations will still end with three games on Saturday but on every other weekend there will be two games on the Saturday and one on the Sunday.
The introduction of Friday night Six Nations has proven controversial.
Wales host England at the Millennium Stadium on 4 February in the first Friday night opener of a Six Nations Championship in its 128-year history.
The clash between the two rivals is also the first time that two Home Union sides will meet on a Friday night as France and Wales have competed in the previous Friday night fixtures in the Six Nations.
France hosted Wales at the Stade de France in 2009 in the first Friday night game in the Championship's history - a 21-16 home win in Paris - before the corresponding fixture - a 26-20 French triumph - in Cardiff in 2010.
The Six Nations' Friday night trial has not been popular with supporters or players but the matches enjoyed bumper viewing figures.
Rail companies warned of potential disruption and some train services look set to be disrupted in the Welsh capital when England visit Wales as rail union RMT has confirmed it will strike on 4 February after talks with Arriva Trains Wales over pay broke down.
So the Six Nations is set to end its Friday night experiment.
"With stadia at full capacity, television is the best way to increase the number of people watching matches," chief Feehan said.
"We feel that the fixture schedules for the next two years will deliver on this."
