I started doing this using as a source a Hebrew book called "Etz Chaim"
(Tree of Life).
I haven't done any work on it in quite some time. I used the Jewish
calendar, starting
at year 1 for creation.

But I would like to clarify some points about John's posting about the
Jewish calendar.
Our year is not 360 days long (that would be way too simple:-)).
The years are 353, 354, or 355 days long, depending on making sure certain
holidays don't fall on certain days of the week (details are beyond the
scope of this
forum). As John said, we have leap years on 7 years of every 19 year
cycle. The
years are the 3rd, 6th, 8th, 11th, 14th, 17th, and 19th years. Leap
years add
an extra 30 day month.

There is most certainly an algorithm to convert the Jewish calendar to
the Gregorian
(probably several). Probably the best known is due to the German
mathematician
Gauss. The algorithm can be found at
http://www.math.technion.ac.il/~rl/docs/gauss.txt (among other places).
Warning - it's quite mathematical....
