The Government has said that it is constitutionally precluded from changing the Presidential Inauguration date from 11 November.
The scheduling of the event later this year has been criticised as it takes place on the centenary of Armistice Day.
The signing of the treaty that ended the World War I is commemorated throughout Europe on 11 November each year.
It has added significance this year as it is the centenary of the end of the war.
The armistice between the Allies and Germany was signed in a railway carriage at Compiègne, France, and took effect on the "eleventh hour of the eleventh day of the eleventh month" in 1918.
Minister for Health Simon Harris said it was a logistical issue but that the Government would reflect on it.
A spokesperson for Minister for Local Government Eoghan Murphy said the date for the inauguration was not a date chosen by the Government.
The dates for the inauguration this year are the same as they were in 2011.
Protocol arrangements are being looked at the facilitate an early inauguration on 11 November, he said.
Labour Party leader Brendan Howlin called for the inauguration date to be changed.
Speaking on RTÉ's News at One, Mr Howlin said the Irish president should be available to stand shoulder-to-shoulder with other heads of states to commemorate the event.
Historian Tom Burnell, who has published a 15-volume list of the Irish killed in World War I, said 11 November should be marked every year as some 30,000 Irish people died on the battlefields of Europe.
Speaking on RTÉ's Morning Ireland, Mr Burnell said the decision to have the inauguration on this date was "ludicrous" as this was the only chance to mark the centenary of the Great War.
The date of the inauguration is determined by the fact that the current president’s term in office ends on 10 November and the ceremony for the new president is held the following day, which this year falls on the 100th anniversary of the ending of the war.
"Our men and women who died during World War I should be remembered on that day," Mr Burrell said.
He explained that the majority of the 30,000 who died came from Dublin (9,000), followed by Cork (4,700).
Mr Burrell said a commemoration should be held in the War Memorial Gardens in Islandbridge.
Glasnevin Trust has said it is working with the Government to ensure its WWI commemoration would not clash with the Presidential Inauguration in order for people to be able to attend both events if they wished.
