In that case I vote that it be changed to "Happy Days" then

Nothing is more religiously neutral than the Fonz

maybe because Christmas celebrates 7th of January in eastern europe?

eeeyyyyyyy - *combs hair

lol, at first I read that like an anime girl screaming, took me a time to click it was the Fonz.

How about AAAAAYYY, that more macho.

​Day comes from the word Dæzikiel, the Christian angel of the sun. So Happy Days wont work either.

That is St Uriel and origins of the word "Day" have been around a lot longer than Christian times. So we are still good with Happy Days ;-)

day (n.)

Old English dæg "day," also "lifetime," from Proto-Germanic *dagaz (cf. Old Saxon, Middle Dutch, Dutch dag, Old Frisian dei, Old High German tag, German Tag, Old Norse dagr, Gothic dags), from PIE *dhegh-.

Not considered to be related to Latin dies (see diurnal), but rather to Sanskrit dah "to burn," Lithuanian dagas "hot season," Old Prussian dagis "summer." Meaning originally, in English, "the daylight hours;" expanded to mean "the 24-hour period" in late Anglo-Saxon times. Day off first recorded 1883; day-tripper first recorded 1897. The days in nowadays, etc. is a relic of the Old English and Middle English use of the adverbial genitive.
