The election should be held on November 29, Green Party leader Roderic O’Gorman has said.
Speaking on Friday, Mr O’Gorman said it was his preference to hold the election before Christmas.
He said: “I think the 29th is the date to go.”
Mr O’Gorman said he will be telling the other two coalition leaders on Monday about the need to “give clarity” to the public.
The Green Party leader said: “I’ve been out on the doors even just last night and I’m starting to get the sense that people are getting a little tired of the ‘will they, won’t they’.
“Probably now is the time to give some degree of certainty to the Irish people in terms of the election date.”
He added: “My preference is for a November election, on November 29. I think that gives us the opportunity to get those final pieces of legislation through.”
Earlier this week, Taoiseach Simon Harris said he is considering what date would be “the best interest for Ireland” while refusing to be drawn on whether that would be before Christmas.
The Fine Gael leader had previously said the Government should “go full term” before an election is called.
While it is the constitutional prerogative of the Taoiseach to decide the date of the general election, Mr Harris has said he will consult the coalition leaders in advance of any announcement.
On Wednesday, Tanaiste Micheal Martin appeared more open to the possibility of a pre-Christmas election if the Finance Bill is passed.
Mr Martin said his view remained that the Government has “work to complete” but added that the gap between November and February “isn’t huge”.
Mr O’Gorman said a dissolution of the Dail could happen in early November following the passing of key pieces of legislation.
He added: “The 29th gives us a clear three weeks and a week after recess to get those final pieces of legislation over the line.”
Following the passing of the Gambling Bill, Mr O’Gorman said his attention was now on the Finance Bill, hate crime legislation and the Maternity Protection Act.
He predicted that the legislation to allow women with serious illnesses to defer their maternity would get through the Oireachtas next week.
Speaking at the same event, Housing Minister Darragh O’Brien said the Government had significant work left to do but added: “I think it can be done in the timeframe that has been outlined by Roderic.”
Asked if he would like the election to be on November 29, the Fianna Fail TD said: “I’m not getting into speculation on dates – that’s above my pay grade.”
He added: “Everyone knows an election is in a matter of weeks or months anyways.”
As the minister with the responsibility for setting the length of the campaign between 21 and 28 days, he said would be guided by the final decision of the three coalition leaders.
