How do you say "Have a nice/great day!" in your local dialect/native tongue?

In Hungarian, we don't have such phrase exactly... but the greeting is similar: "Good day" (as hello) is "Jó napot" or "Szép napot".

Loads of ways in Irish, no real direct translation I'm aware of though. Then again, I only have classroom knowledge of the language.

Slainte chugat = Good Heath or you can just say Slainte.

Saol fada chugat = May you live a long life

Slan abhaile = Have a safe trip home

Slan agus beannacht leat = Goodbye and Bless You.

My own very special dialect of Dutch/English/Anime-Japanese..:

Buhbaaaai! Have a nice day! Nyaaa..

My native language:

Een prettige dag nog! (informal)

Que tenga buenos dias= spanish

Ya'll have a good day now you hear. I'm from the south. Actually I just say have a great day.

In German we would say:

To a friend:

Ich wünsche dir einen schönen Tag!

To somebody you don´t know:

Ich wünsche Ihnen einen schönen Tag!

I hope I could help you!

Nice day!

Although there are literal equivalents, there is no such phrase in the same manner in my native language.

Buona giornata!

It's Italian

Lijepo se provedi! (that would be more like have a nice time but it`s the closest translation).

اليوم كان حلو كتير ( Arabic)
