Today, voters will be asked whether or not they want to lower the age requirement for presidential election from 35 to 21, they will also be asked whether or not they wish to legalize gay marriage.
This referendum is being dubbed as 'the young persons' referendum' and as a result a large amount of young people will be voting for the first time.
Here are a few things you may not have thought of to ensure you cast a valid vote this Friday.
Polling card
These will have been sent out to your registered address ahead of Friday's vote. On it will give the location of your voting booth, something worth noting.
As well as this, voters will have received independent documentation from the Referendum Commission. This is vital reading and should contribute to help making you your decision.
If you don't have you polling card you can check your polling station by visiting Check the Register.
What to bring
You don't need to but it won't hurt to bring the aforementioned polling card. However, you will need a form of valid personal identification such as a passport or a driving license when you go to vote.
Electoral paraphernalia
Campaigning at voting booths is prohibited. Laws are in place to ensure that no posters or any other electoral merchandise encouraging either side is within a 50 meter radius from the booths.
If you arrive donning a yes or no badge you will be asked to remove it by people at the polling station as it is their duty to do so.

No yes or no merchandise is not allowed near the polling stations.
Ballot papers
Once you've arrived and given your ID you will then be given two ballot papers, one on marriage equality and one on presidential age.
After carefully reading both ballots you may then mark both with an X. Both ask you if you approve of the proposal so if you are in favour mark the X in the 'TÁ or YES' box. If you do not approve, place the X in the 'NÍL or NO' BOX.
After that fold the paper in two and place it in the ballot box.
Do not take a picture of the ballot paper or yourself in the polling booth as it may render your vote invalid.
