Small translation asked (a) Oh before you get mixed up, don't translate this message, just check my one turkish sentence

Hi there

Saturday it's Queen's Day in Holland, the only form of (awful Dutch) nationalism, apart from the football-stuff

I'm gonna go for a drink in the turkish restaurant where i used to work last summer before i go out at night. (no i'm not part of the orange-shirted-jumping-screaming-mass, i'll just go out, dance and eat orange cotton-sugar )
Now i'd like to say the following to my old colleagues as they were always complaining about the Queen, but this is the only dutch feast-day that they actually celebrate a bit:

Kraliçenin Doğum Günün kutlu olsun

Is that correct? It's meant as a joke which they will surely understand because of former discussions i had during shifts about the Dutch royalty hehe.

Can somebody check this one sentence for me please?

Kraliçenin Doğum Günün kutlu olsun

This is like: "happy birthday to Queen"?

Queen's Day = Kraliçe Günü
may your Queen's day be nice: Kraliçe gününüz iyi geçsin.

We dont have a Queen's day so it is maybe like congratulations:
I congatulate your Queen's Day:
Kraliçe gününüzü kutlarım

Or would you suggest something else/better?

May your Queen's bday be nice
- kraliçe gününüz güzel/iyi olsun..
(~kraliçe gününüz güzel/iyi geçsin )

happy birtday to your queen
- Kraliçenizin doğum günü kutlu olsun..

happy queen's birthday to you
- mutlu kraliçe günlerine..
(~mutlu kraliçe günleri dilerim )

Thanks
