Hi I am trying to understand that there is a difference the way chinese calculate thei r new year the Chinese method, if anyone is born before the 1st 10 days of Feb, he or she belongs to the previous year. Western Calender: 1st Jan to 31st Dec. Chinese Year: Any dates between late Jan or 1st 10 days of Feb. To the next year Jan-Feb (1st 10 days Feb). The 12 months are shifted to start in late Jan or Feb. Eg a person born on 11 Jan 1965, his Chinese date is 16 Dec 1964. So the Kua number has also changed. So the accuracy is out. is there a way that a formula can be used to achieve this Thank you in anticipation for the help kind regards rajan
