按农历算
你说的口算法不适合计雹孙算机语言，要在VB里处理还是建议你用楼上的方法，简单、快速。
下面给你口算方法，你看下，做个了解，需要一些口算能力，或是算命的，他们整天算这些，超级快。
利用公式推算阴历日期：
设：公元年数－1977（或1901）＝4Q＋R
则：阴历日仔局期=14Q+10.6(R+1)+年内日期序数-29.5n
（注:式中Q、R、n均为自然数，R<4）
例：1994年5月7日的阴历日期为：
1994－1977＝17＝念肆让4×4＋1
故：Q＝4，R＝1 则：5月7日的阴历日期为：
14×4+10.6(1+1)+(31+28+31+31+7)-29.5n
=204.2- 29.5n
然后用29.5去除204.2得商数6......27.2，6即是n值，余数27即是阴历二十七日。
