Can I send Happy New Year to others on New Year's Eve? Or tomorrow is the New Year?

Today is very good. I'm 30 years old and welcome the new year on New Year's Eve. We have begun to pay New Year greetings in advance. We can pay tribute to the early years, or we can do it tomorrow. Tomorrow is the official Chinese New Year, and it is ok to pay a New Year call. The atmosphere is the most important, no matter what day. I will also pay a New Year call to all of you here. In the new year, we will realize all our wishes, get rich, have a happy family and have all the best.
