Ancient Jewish Computers

In perfecting Judaism’s complex, lunisolar calendar,
the Rabbis likely relied on advanced mathematics.

Passover, the Bible tells us (Exodus 34:18), is Hag Hamatzot (Holiday of The Matzot) whose time is Mo’ed HaAviv, a spring festival, that begins on the 15th day of Nisan, on the night of a full moon after the vernal equinox (“Tekufat HaShana”), following the Passover sacrifice on the 14th. 
A computer nerd, I have always been fascinated by the Jewish calendar, perfected about 1,650 years ago, and I've always wondered how such complex calculations could be accomplished in the pre-computer age. 
I've recently discovered how, and it's a fascinating story.
