The eyes of the world are on Ireland, as hundreds of journalists file stories to audiences across the globe on what happens in the referendum result.
Ireland could be the first country in the world to legalise same-sex marriage by popular vote.
The news and views of Irish people are being beamed across the world by the BBC, AFP, CNN, Channel Four and others as voting gets underway.
So how is the referendum on same-sex marriage seen abroad?
The London bureau chief for the Washington Post, Griff Whitty, says there is huge interest in the referendum in the US, because of the interest there in gay rights.
Ireland correspondent with the Guardian and Observer, Henry McDonald, says the international media is descending on Ireland at the moment.
While The New York Times - who made it front page news earlier this week - want to hear from readers in Ireland.
In a post on their official Facebook page, the paper said: "How is this issue being discussed in your own family? How are different generations reacting to the referendum?"
Jerry Condon commented: "This is about one issue only, equality. Ireland claims to be a republic, a term that has been sullied by violence here for years. A true republic cherishes all its citizens. I am confident we will take this bold step with pride on Friday."
Stephen Hamilton said: "Most people in Ireland have the heart to say this is the right thing to do as what kind of a society disallows equality? Vote yes".
While Tracy Symonds-Keogh said: "It's a YES vote from my family, my friends and I sincerely hope for the majority of voters. Also brilliant to see younger voters motivated to be heard. As a side note for a country that covets the Eurovision how could anyone in good conscience vote No!".
Maximum Homosapien commented: "Intolerences never before openly expressed have been spoken by friends, family, and loved ones. Parents have taken their yes-voting children off the electoral register or torn up their polling cards. Your sweet old grandfather is sweet no more as he hectors you to remember your pledge to Jesus and vote no for Christ. An unmasking, of a kind has taken place".
And Evert Bopp wrote: "Absolutely voting "No" tomorrow. Have discussed the issue at length with all our kids, and some of their friends (some of which are gay)...They understand the wishes of gay people to get married but don't think it's the right thing."
