Chinese New Year 2010 falls on 14th of February, 2010. The Chinese New Year is celebrated as the symbol of spring's celebration. In fact, in China the Chinese New Year is still called the Spring festival. It is celebrated after the fall harvest and before the spring planting season. The date of the Chinese New Year is always changing and is dependant on the Chinese calendar. Emperor Huangdi in the year 2637 B.C.E invented the Chinese calendar.
The Chinese calendar is a combined solar/lunar calendar and is somewhat similar to the Chinese calendar. For the purpose of determining the dates of the Chinese New Year some astronomical calculations need to be taken care of. Firstly, we need to determine the dates for the new moon. The new moon is the black moon that is when the moon is in conjunction with the sun.
The date of the new moon is taken as the first day of the new month. Secondly those dates are determined when the sun's longitude is the multiple of 30 degrees. These dates are termed as Principal terms and are used for determining the number of each month.
