If an artist blows up in november/December, are they artist of the year or next year?

It seems like November and December is very late in the year so I am just curious if it's still their year.

Did anyone ever won like this? If so than you got your proof

Kim Gunmo released an album in November 1993 but it counted as a 1994 disk daesang. Nevermind, I answered my own question.
