How do you make calendar show the age of your father? I put %%(diary-chinese-anniversary 12 1 1952) in my diary file and on 2008.12.27 (solar calendar), it says '56 years old', isn't this correct? There are different ways of counting ages. The diff var in the diary-chinese-anniversary holds the age value. Incidentally I found a bug in diary-chinese-anniversary. Could you test the attached version?
