On the topic of the "Night" thing, I entered 月夜 into Denshi Jisho to see if there's any other way it could be interpreted, and apparently the word is also used for a species of ghost fungus, a type of mushroom that glows at night (月夜茸). The term is translated on Jisho as the Moonlight Mushroom, and other countries have similar naming themes for it (such as the Jack O' Lantern Mushroom).

I'm not saying this proves that "Tsukiyo" means "Moonlight" and not "Moonlit Night"--It still clearly means "Moonlit Night". But I'm saying there does appear to be a precedent for shortening the term as to cut out "night" and focus entirely on the moon aspect of it when used as a descriptor for other things.
