Convert a Jewish date to a Julian Day Count:
The jewishtojd() function converts a date from the Jewish Calendar to a Julian Day Count.
Note: Although this function can handle dates back to year 1 (3761 B.C.), notice that in the beginning there was no formula to determine the start of a month. A new month was started when the new moon was first observed.
Tip: Look at the jdtojewish() function to convert a Julian Day Count to a Jewish date.
