Hello all, and thank you for the great resource of education and entertainment this forum provides!

I am attempting to translate an important date from english to irish gaelic, so I am going for a more formal approach as opposed to the casual way we are probably more prone to speak.

Here is what I have so far, and I'd greatly appreciate if you guys could confirm, or more likely, correct me on the accuracy of what I have come up with on my own.

"Tuesday, the twenty-fifth of August, two thousand (and) fifteen"

"Dé Máirt, an cúigiú is fiche de Lúnasa, dhá mhile is a cúig déag"

Thank you in advance for your time!

Here ya go:

Dé Máirt an cúigiú lá is fiche de mhí na Lúnasa, dhá mhíle is a cúig déag

That looks excellent, certainly much better than my attempt.

Thank you very much!!
