Future enrollment in a CV TL;DR

Is it okay to list a university and an expected degree in my CV (under the education section), if the semester starts a month from now?

Longer verion:

I have finished bachelor studies and got accepted in a master program which starts in a month. I feel that if I leave out the master program because the semester and the classes have not actually started yet, the CV might look a bit empty.

Is it appropriate to list the imminent master studies as well?

Should I avoid having a specific starting month and simply put the year I enrolled, even if the semester is very close and it is highly unlikely that I will not attend?

Would the answer differ in industry?

If the semester was further away, more than a month, but I got the acceptance letter, is it still okay to list it?
Under Education, presumably you have a line for your Bachelor's.  You may also put a line for your Masters study -- perhaps something like this:

Start date: October, 2015 (tab) (name of degree, name of institution)
