That still makes more sense than what we do now.

Then there is the Hebrew lunar calendar:

which adds an extra leap month in 7 out of every 19 years (3, 6, 8,
11, 14, 17, and 19):

Being able to handle such an ugly calenadar might explain why Jews are
quite good at finance. Can you imagine what a loan amortization
schedule looks like under such a calendar?

No, jews are good at finance because the catholic church banned christians
from usury - lending money and charging interest. As money became more and
more important it became necessary for there to be financiers but christians
weren't going to risk lending their money free of charge. So jews were
invited into most catholic / christian countries to be the financiers as
they had no such rule in *their* holy book. Without jews stepping in to
finance large projects we'd still be in the dark ages.

Yet how do we thank them? By making thinly-veiled anti-semetic jokes in
electronics repair groups (and probably other places as well).
