The Taoiseach has announced that the Children's Referendum will be held on Saturday 10 November.
Enda Kenny told the Dáil that the wording had been agreed at this morning's Cabinet meeting.
It will be discussed with Opposition parties before being published at around midday tomorrow.
A Government spokesperson confirmed that there will be a Government information campaign alongside that carried out by the Referendum Commission.
Mr Kenny said the Government was committed to ensuring that people had all the information they needed and the Referendum Commission would be well resourced.
He said there had been good cross-party co-operation on the issue over many years.
Mr Kenny said the referendum proposals, along with other reforms under way to improve child protection and welfare services, would be an historic step forward.
The only other referendum to be held on a Saturday was the second referendum on the Nice Treaty, which was held on Saturday 19 October 2002.
Iona Institute Director David Quinn said the group would wait to see the wording of the amendment before it takes a position.
Mr Quinn said: "As we have said before, we would have concerns about a wording if it made it too easy for the State to intervene in the lives of families."
But campaign groups representing children have welcomed the news.
Director of Services with the ISPCC and member of 'Yes for Children' Caroline O'Sullivan said that they are absolutely delighted that a date has finally been set.
She said organisations such as the ISPCC, Barnardos, and The Children's Rights Alliance have been campaigning for a referendum for children to take place since the 1990s.
The Adoption Amendment Bill will also be published tomorrow, as will details of the Referendum Commission, including who will chair it.
