0. Syntax: [JD,julianday] = juliandate(year,month,day,hour,min,sec)

1. Inputs:
year, month, day = date in Gregorian calendar.
hour,min,sec = time at Universal Time.

2. Outputs:
JD = Julian date.
julianday = day of week.

3. Example:
>> [a,b] = greg2julian(2006,5,30,2,30,28)
a =
2453885.60449074
b =
Tuesday

4. Notes:
- For all common era (CE) dates in the Gregorian calendar, and for more information, check the referents.
- 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.
