1. Inputs:
JD = Julian date.

2. Outputs:
year, month, day, dayweek = date in Gregorian calendar.
hour, min, sec = time at universal time.

a =

b =
6
c =
1
d =
2
e =
30
f =

g =
Thursday
h =

4. Notes:
- For all common era (CE) dates in the Gregorian calendar.
- The function was tested, using the julian date converter of U.S. Naval Observatory and the results were similar. You can check it.
Trying to do the life... more easy with the conversions.
