PHP - Function jewishtojd ()



int jewishtojd ( $month, $day, $year );

Definition and Usage

Converts a date in the Jewish Calendar to Julian Day Count. Although this function can handle dates all the way back to the year 1 (3761 B.C.), such use may not be meaningful. The Jewish calendar has been in use for several thousand years, but in the early days there was no formula to determine the start of a month. A new month was started when the new moon was first observed.


Parameter Description
month Required. The month as a number from 1 to 13
day Required. The day as a number from 1 to 30
year Required. The year as a number between 1 and 9999

Return Value
