Leo Varadkar and Micheal Martin will hold their crunch election date meeting on Thursday evening.
A senior source has this afternoon told the Irish Daily Mirror that both sides have now agreed to the timing of the meeting for Thursday.
There is basically only one thing on the agenda - the timing of the next general election.
Both leaders have said they would prefer an election in April or May, but ultimately the decision lies with Mr Varadkar as Taoiseach and he could call a February election as early as this week.
The Mirror revealed before Christmas that the orders for the printing of ballot papers to be ready for polling stations by February 1st are in.
If the Dail is to realistically last any longer than January, a deal will have to be struck between the leaders at the make-or-break meeting on Thursday.
The pair of politicians have been communicating via letters which have found their way into the media over the past month.
This will be the first time they will actually sit down face-to-face to discuss what everyone in the country wants to know - when is Election Day?
Mr Varadkar has said that Fine Gael want closure on a number of issues, including an agreement on property tax policy, the passing of effective climate action legislation and the completion of special Dáil inquiries into votergate, the alleged irregular voting of Fianna Fail Dail deputies.
Mr Martin will want assurances that there is a procedure where Dara Murphy will be held to account for his double-jobbing in Brussels and Dublin while claiming massive expenses of over €50,000 a year from the taxpayer.
He also has a shopping list of legislation Fianna Fail wants passed before Easter.
If negotiations break down, Leo has already scheduled a special meeting of the Fine Gael parliamentary party for this Friday.
If the Taoiseach and Mr Martin have a row, Leo could use this meeting to send his troops to the country.
