China does not necessarily have a different calendar. They use the common calender as most of the world does (same number of months and weeks, etc), but also uses the Lunar Calender.
If you are referring to the Chinese zodiac, well, that is not their calendar.
we celebrate it in different days in the years
It is the new year based on the Chinese traditional calendar, like the new year we celebrate on 1st January every year, only on a different date.
The Chinese New Year (CNY) is determined by Lunar calendar instead of sun calendar.So each year,the date to celebrate is different. To put it simply,the CNY often occurs during Jan-Mar.
they are different because they are really celebrated by different types of people and they have different gods and celebrate it in a different way...
January or Feb. depending on the year because the Chinese New Year is on a different date each year due to the fact that the Chinese calender follows the moon. 2010 = Feb 14 2011 = Feb 3
It's the same reason that people celebrate Easter or Christmas: it is their tradition. If you are Chinese or are interested in Chinese culture/traditions, you may celebrate Chinese New Year. It is just like westerners celebrating our new year except the Chinese choose to use a different date.

The Chinese new year is on a different date every year because it is based on the Chinese calendar, known as the lunisolar calendar. Typically date systems are usually based upon the Gregorian calendar.
This is never possible as people around the world celebrate Chinese New Year at the same time, however, it is a different date on every year. Think of it as would you celebrate new year on a different date in America and in Australia?
people celebrate Chinese new year is because Chinese new year is their tradition.
