Boys! How about this as a Solomonic definition we can all
live with?

Julian Day has a specific meaning spelled out on the
USNO web page. But since no one reads it or remembers
what it is, and uses it ten ways to Sunday differently,
you assume that definition in your programming at your
own peril.

Does that help? :-)

Cheers,
