"A few days every month, he goes cycling."
Is the noun phrase "a few days every month" acting as an adverb to "goes" in the above sentence? There is no preposition before the noun phrase "a few months every year" that may make it an adverbial phrase. So how is the sentence without a preposition in the present form correct grammatically?

It is an adverbial phrase, just like the ones Brian mentioned, but in some sense it does not modify the verb but the whole sentence "he goes cycling". A clearer example is "Obviously, he ran off.", where "obviously" does not describe the way "he ran off" but rather describes that the fact that "he ran off" was an obvious one.
Also, a prepositional phrase can be used as an adverb but not all adverbial phrases are prepositional. "He runs quickly" has an adverb "quickly".
