Is there a lucky number in Ireland?

Question

Seven is lucky and thirteen is unlucky in the US. Eight is lucky in China, while four is unlucky. In Japan, three is lucky and nine is the luckiest.

Answer 1

Yes, 4 is lucky,,,for example the 4 leaf clover!

Answer 2

In Italy 13 is lucky and seventeen is unlucky.

Not sure about Ireland but from how I know the Irish, if you want them to do something for you tell them to do the exact opposite and they'll comply.

So, going by that, tell them that seventeen is unlucky in Italy and chances are they'll make it their lucky number.
