I don't think so, New Year Greeting topic is very common on internet. There are various old dedicated sites in this niche. Ranking a 2-3 day old blog in this niche is almost impossible. One more thing is that it is not a profitable niche if you want to earn money. Instead of wasting your time in this niche, try to create micro-niche blog on an upcoming electronic product like smartphones, tablets, laptops etc. These topics will give you more money, even if you got less traffic.
