First of all, you need to let us know what you mean by Julian Date. Do you mean the
True Julian Date, which starts on Noon (12:00 on January 1, -4713,
Modified Julian Date, which starts at Midnight on November 17, 1858, or
Comtemporary Accepted Julian Date, (contemporary accepted is my term, because this is not truly a Julian date) which is a five digit number with the first two digits representing the year, and the next three for the day within the year?
Good Luck
