Charles,
I built a whole series of Julian Date Format functions that are available as UDFs at
the www.cflib.org web site.
JulianDayofWeek: Returns the day of the week for a date in the Julian calendar.
Returns the day of the week for a date in the Julian. If no date is provided, defaults
to the current day. Verified to be accurate between 400 and 9999 AD.
GetDateFromJulianDay: Calculates the date and time from a provided Julian Day value.
GetDateFromModifiedJulianDay: Calculates the date and time based on a modified Julian
Day.
GetJulianDay: Calculates the Julian Day for any date in the Gregorian calendar.
This function calculates the Julian Day for any date in the Gregorian calendar.
Astronomers have used the Julian period to assign a unique number to every day since 1
January 4713 B.C.E. Julian Days begin at noon on the date specified
GetModifiedJulianDay: Calculates the modified Julian Day for any date in the Gregorian
calendar.
Calculates the modified Julian Day for any date in the Gregorian calendar. Sometimes a
modified Julian day number (MJD) is used which is 2,400,000.5 less than the Julian day
number. This brings the numbers into a more manageable numeric range and makes the day
numbers change at midnight UTC rather than noon. MJD 0 thus started on 17 Nov 1858
(Gregorian) at 00:00:00 UTC.
I hope these help. Good luck.
Beau

Does someone have a function built to convert the current date to a julian
format?
Thanks,
