Is it correct?
> In December I sleep whole days
No, in American English you would say "the whole day" or "all day"
It's just the same in British English: You don't need a plural as you're describing a habitual activity. Possibly not a good habit...
"I'm asleep all day" should be accepted, no?
Why not : I sleep all day in December?
Should it not be pronounces as "ba detzember" instead of "bey detzember" since months are inherently definite?
"Be" becomes "ba" only if ה is included. Since months, as you wrote, are definite already, you don't add the ה and therefore it stays "be".
