one method is to have: 9 8 7 6 5 9 8 7 6 5 maps to 甲乙丙丁戊己庚辛壬癸 and 9 8 7 6 5 4 9 8 7 6 5 4 maps to 子丑寅卯辰巳午未 申酉 戌亥
then e.g. for 甲子乙丑, add them together, gets 9+8+9+8 = 34. divided by 5, remainder is 4, and then, I forgot ... but it's documented in many books.
the 2nd method is based on previous method, and using the "palm" to aid the calculation, and should be able to count the result within 2-5 seconds. It's quite hard for me to illustrate here though ... it's maths, anyway. not hard to derive oneself. This method is documented in 1 or 2 books only -- the books I have read so far.
But I have to admit that if you have good memory, 方法一 is a good way.
And finally, my suggestion is, to prepare a cheat-sheet ... or, save it in PDA...

有勞stevie兄的介紹。
