(12C) HP 12C: Julian Date - Eddie W. Shore - 02-11-2015 02:21 PM
The Julian Date of any calendar date D can be found by:
dDYS(January 1, 2000; D) + 2451545
d represents the Delta Symbol (Δ) for ΔDYS
It is assumed it is 12:00 Universal Time.
This program should work in either D.MY and M.DY mode:

To be precise: it's the Julian day number.
Eddie, if you use the "code" tag (the "#" symbol on top of the edit window) your listing will appear correctly formatted. Since the forum's editor uses a proportional font you should enter the program in an externel text editor and copy it back when you're done. Yes, this really is a nuisance, but there is no other way unless the forum software uses a fixed font.
