Julian历法的合理年份为 4713 B.C. 到 9999 A.D.

尽管这个函数也可以处理4713 B.C.以前的日期，但是没有意义。这个历法是在46 B.C.创立，但是到了8 A.D.还没有稳定，可能直到第4世纪才最终完善。而且，每年的开始也不相同，不是所有的国家都认定January为第一个月份的。

记住，当今世界最广泛使用的历法是Gregorian历法，函数<span class="function"><a href="gregoriantojd.html" class="function">gregoriantojd()</a></span>可以转变日期为Julian Day计数。
