Minister for Children Frances Fitzgerald has said she hopes students in particular will come out in force on Saturday 10 November to vote for the Children's Referendum.
Ms Fitzgerald was speaking as she officially launched a website dedicated to information on the referendum this afternoon.
The website includes the referendum wording, as well as a guide to the proposed changes.
It also has factsheets on topics such as adoption and foster care, and answers to frequently asked questions about the referendum.
It has both Irish-language and English-language versions.
Ms Fitzgerald said the Government had received a lot of support in the Dáil and was now looking for the support of the public to pass the referendum.
She said she hoped the Saturday date will attract more voters, and that it is now up to university students, who have always looked for a Saturday election, to come out and vote.
She said the Government will have to see what the impact of a Saturday vote is.
