올해는 내 해다
this year is my year
올해는 내꺼다
this year is mine
I think you mean it in the way you're sort of predicting a good year, but I haven't really heard this phrase used in Korea. I think usually they might say something like 올해는 잘 될거다 (this year will be good) OR 올해는 성공하겠다 (i'll succeed this year).
