Commenting on the fixtures for the 2012 and 2013 Championships, Six Nations Chief Executive John Feehan said: "Our schedules aim to deliver as much great rugby as possible to the supporters.
"With stadia at full capacity, television is the best way to increase the number of people watching matches. We feel that the fixture schedules for the next two years will deliver on this."
Ireland will start the 2012 Six Nations at home to Wales, and play France (away), Italy (home) and Scotland (home) before concluding with a St. Patrick's Day finale against England at Twickenham.
In 2013, Ireland will visit Cardiff for their Championship opener, and games against England (home), Scotland (away), France (home) and Italy (away) will follow in that order.
All of Ireland's matches will take place either on a Saturday or Sunday, with the Six Nations Council deciding to end the experiment regarding Friday night games, which has run for the past two years.
The 2011 RBS 6 Nations opens on Friday week (February 4) when Wales host England at the Millennium Stadium.
