I'm not exactly sure. But, the notes you give line up pretty closely to "Have Yourself a Merry Little Christmas." The only notes that would be incorrect is the 4th note -- it should be a C instead of a B -- and the last note, which (if this is the song you are thinking of) would be a D instead of a C.
The Christmas song is a carol.

The Christmas song with the initials Z C is "Zither Carol". The song is a Bohemian/Czech Carol. There are at least two versions of the carol.
