摘　　要：在历法计算和易经应用中,由于公历纪日和干支纪日方法不同,如何将公历任一日迅速准确地转换成干支是十分复杂的问题,目前主要借助于万年历解决。经过悉心研究,总结并抽象出求解公历任一日干支的数学公式,准确科学简单实用,实现了人们千百年来"不用万年历,日柱早知道"的愿望,从而也解决了"脱离历书求四柱"的问题。该公式可简称为《张云鹤日柱公式》或《张云鹤日干支公式》。In the application of The Book of Changes and calculations of the calendar systems, it is a great complex issue to convert accurately and speedily a certain day from the Gregorian calendar into the Heavenly Stems and the Earthly Branches, owing to the great difference in numbering the day between the two systems. And at present it can only be done with a perpetual calendar. Now the author of the paper, after years of research and with pains -taking efforts, has established a mathematical formula with which the above mentioned problem can be solved with ease and accuracy, thus realizing the long - cherished wish ＂telling the day without consulting the perpetual calendar＂ and solving the problem of ＂relying on almanac for the requirement of one＇s four elements of birth time （ year, month, day and time） ＂. This formula is called ＂Zhangyunhe Rizhu Formula＂ or ＂Zhangyunhe Riganzhi Formula＂ in short.
