Chinese New Year begins according to the Chinese calendar which consists of both Gregorian and lunar-solar calendar systems. Because the track of the new moon changes from year to year, Chinese New Year can begin anytime between late January and mid-February.
The Lunar New Year dates from 2600 BC, when the Emperor Huang Ti introduced the first cycle of the Chinese zodiac.
Because of cyclical lunar dating, the first day of the year can fall anywhere between late January and the middle of February. On the Chinese calendar, 2011 is Lunar Year 4709.
On the Western calendar, the start of the New Year falls on Thursday, February 3, 2011 — The Year of the Rabbit.
