JDay(date) . . .
calculates the Julian day from the Gregorian Calendar
(the calendar we currently use) espressed in
YYYYMMDD.DD format (the .DD is the decimal
fraction of the day). The Julian day for a date is the
number of days that have elapsed between the date
and January 1,4713 BC. The elapse number of days
between two dates is simply the difference between
their Julian day numbers.
