From what time ?

Should I say ''Nanji kara ?'' or ''Nanji kara desu ka ?''

From August.

Should I say ''Hachi gatsu kara desu.'' or ''Hatchi gatsu kara.''

My book gives it without the ''desu'' but I just feel it might be a bit
abrupt.

I'm a beginner btw

question
grammar words
Does ''desu'' and ''desu ka'' go with ''kara''?
I think this is a good question.

  1. 何時から? Nanji kara?
  2. 何時からですか? Nanji kara desuka?

Both are the valid and correct, however, #1 is mostly in oral and #2 is always
used in formal and oral. In other words, #2 is more polite than #1.

  1. 8月から
  2. 8月からです

The same explanation of above.
