It's "Hyvää joulua" or "Hauskaa joulua". Happy New Year is then "Hyvää uuttavuotta".
Gelukkige Onafhankelijkheidsdag is the word for Happy Independence Day. This is translation from English to Dutch.
Vrolijk Halloween
I would say: 'Happy thanksgiving'. Because Thanksgiving is an American holiday, not a Dutch, there is no specific translation for it.
Christmas = Navidad
'Happy birthday' is 'fijne verjaardag' in Dutch.
Heb een fijn leven.

feliz novo de natal
Do you mean how do the Dutch say it?? If so it is Gelukkige Bithday.
In belgie they are talking 3 language , one of them is dutch.. in dutch we say: ik wens u een gelukkig nieuwjaar ( i wish u a good newyear)
Nobody is always happy. Dutch children are also not always happy.
