The original game was abandoned just 10 minutes before kick-off in Paris on Saturday because the frozen pitch was considered dangerous.
The change to the schedule means Ireland must play Scotland six days after visiting the Stade de France, with the IRFU upset organisers did not hold the game a day earlier to allow for more recovery time.
An IRFU statement read: “We are disappointed with this decision. While understanding the difficulties that a postponed game brings to the international and club rugby schedule, the IRFU had proposed to the Six Nations that the preferred alternative date would be Saturday 3 March with an afternoon kick-off.
“This was based on providing the Ireland team, who will be travelling for a second time to Paris, with a seven day turnaround between its remaining four fixtures in the tournament.
“It would also have provided any supporters wishing to attend the rescheduled game with an appropriate window of travel.”
Six Nations chief executive John Feehan expressed his regret that many supporters were left disappointed, after referee Dave Pearson’s late decision to abandon the game.
“We very much regret what has happened. This is not something anybody would have planned for or would have wished to happen,” Feehan said.
“It’s deeply disturbing. It’s terrible that it happened. It has happened and we’ve got to look at how it happened and make sure it doesn’t reoccur.”
“We’re going to have to revisit our procedures for calling a game off.”
