The Chinese refer to the beginning of spring as Li Chun or Lup Chun立春. Every year, it falls mostly on 4th February but there will also be years when it is on the 3rd of February in 2017 is such a year. This is the time when the 9 Flying Stars will relocate to the different sectors assigned for the year. Feng Shui enthusiasts would start to rearrange Feng Shui remedies and enhancers in their new positions in order to protect against the ill effects of the bad stars and to boost the positive vibes of the auspicious ones.
In Chinese astrology, we only consider those born on or after Lup Chun day as belonging to the Zodiac sign of the year and not on the Lunar New Year.
There will be two Lup Chun's in the Rooster Year. Now this is auspicious. In Chinese it is known as Shuang Chun Nian (double spring year). A year without Lup Chun is known as Mang Nian or Blind Year. It is considered inauspicious and couples are advised not to marry during such a year.
