Tips and Notes
Note: Although this function can handle dates back to 4714 B.C., you
should notice that the Gregorian calendar was not instituted until 1582, and
some countries did not accept it until much later (Britain converted in 1752,
USSR in 1918, and Greece in 1923). Most European countries used the Julian
calendar prior to the Gregorian.

<?php
$jd = gregoriantojd(10,3,1975);
echo($jd . "<br />");
$gregorian = jdtogregorian($jd);
