Convert a Julian date to a Julian Day Count and back to a Julian date:
The juliantojd() function converts a date from the Julian Calendar to a Julian Day Count.
Note: Although this function can handle dates back to 4713 B.C., notice that the Julian calendar was created in 46 B.C., and it did not stabilize until at least 8 A.D. Also, the beginning of a year varied from one culture to another - not all accepted January as the first month. Remember that the current calendar being used worldwide is the Gregorian calendar. The gregoriantojd() function can be used to convert such dates to their Julian Day count.
Tip: Look at the jdtojulian() function to convert a Julian Day Count to a Julian date.
