swe_date_conversion():
This function converts some date+time input {d,m,y,uttime}
into the Julian day number tjd.
The function checks that the input is a legal combination
of dates; for illegal dates like 32 January 1993 it returns ERR
but still converts the date correctly, i.e. like 1 Feb 1993.
The function is usually used to convert user input of birth data
into the Julian day number. Illegal dates should be notified to the user.
Be aware that we always use astronomical year numbering for the years
before Christ, not the historical year numbering.
Astronomical years are done with negative numbers, historical
years with indicators BC or BCE (before common era).
Year 0 (astronomical) = 1 BC historical.
year -1 (astronomical) = 2 BC
etc.
Many users of Astro programs do not know about this difference.
Return: OK or ERR (for illegal date)

* This function returns the absolute Julian day number (JD)
* for a given calendar date.
* The arguments are a calendar date: day, month, year as integers,
* hour as double with decimal fraction.
* If gregflag = SE_GREG_CAL (1), Gregorian calendar is assumed,
* if gregflag = SE_JUL_CAL (0),Julian calendar is assumed.
The Julian day number is a system of numbering all days continously
within the time range of known human history. It should be familiar
to every astrological or astronomical programmer. The time variable
in astronomical theories is usually expressed in Julian days or
Julian centuries (36525 days per century) relative to some start day;
the start day is called 'the epoch'.
The Julian day number is a double representing the number of
days since JD = 0.0 on 1 Jan -4712, 12:00 noon (in the Julian calendar).
Midnight has always a JD with fraction .5, because traditionally
the astronomical day started at noon. This was practical because
then there was no change of date during a night at the telescope.
From this comes also the fact the noon ephemerides were printed
before midnight ephemerides were introduced early in the 20th century.
NOTE: The Julian day number must not be confused with the Julian
calendar system.
Be aware the we always use astronomical year numbering for the years
before Christ, not the historical year numbering.
Astronomical years are done with negative numbers, historical
years with indicators BC or BCE (before common era).
Year 0 (astronomical) = 1 BC
year -1 (astronomical) = 2 BC
etc.

(The parameter sequence m,d,y still indicates the US origin,
be careful because the similar function date_conversion() uses
other parameter sequence and also Astrodienst relative juldate.)

function calc():
This is the main routine for computing a planets position.
The function has several modes, which are controlled by bits in
the parameter 'flag'. The normal mode (flag == 0) computes
a planets apparent geocentric position in ecliptic coordinates relative to
the true equinox of date, without speed
Explanation of the arguments: see the functions header.
Returns OK or ERR (if some planet out of time range). OK and ERR are
defined in ourdef.h and must not be confused with TRUE and FALSE.
OK and ERR are of type int, not of type AS_BOOL.
Bits used in flag:
CALC_BIT_HELIO 0 = geocentric, 1 = heliocentric
CALC_BIT_NOAPP 0 = apparent positions, 1 = true positions
CALC_BIT_NONUT 0 = do nutation (true equinox of date)
1 = don't do nutation (mean equinox of date).
CALC_BIT_SPEED 0 = don't calc speed,
1 = calc speed
Time range:
The function can be used savely in the time range 3000 BC to
3000 AD.
Getting ecliptic and nutation:
calc(CALC_ONLY_ECL_NUT,teph,0,&nutv,&meaneklv,&eklv,NULL);
will return the values for time teph.

This should only be used for porting older Placalc applications.
All new applications should directly use the Swiss Ephemeris API.
A programmer using the Placalc API needs only to include this file

There is no documentation, as it is only intended for porting old

The Placalc API is not supported in the Windows DLL versions of
Swiss Ephemeris.

/*************** julday ********************************************
* This function returns the absolute Julian day number (JD)
* for a given calendar date.
* The arguments are a calendar date: day, month, year as integers,
* hour as double with decimal fraction.
* If gregflag = 1, Gregorian calendar is assumed, gregflag = 0
* Julian calendar is assumed.
*
The Julian day number is system of numbering all days continously
within the time range of known human history. It should be familiar
for every astrological or astronomical programmer. The time variable
in astronomical theories is usually expressed in Julian days or
Julian centuries (36525 days per century) relative to some start day;
the start day is called 'the epoch'.
The Julian day number is a double representing the number of
days since JD = 0.0 on 1 Jan -4712, 12:00 noon.
Midnight has always a JD with fraction .5, because traditionally
the astronomical day started at noon. This was practical because
then there was no change of date during a night at the telescope.
From this comes also the fact the noon ephemerides were printed
before midnight ephemerides were introduced early in the 20th century.
NOTE: The Julian day number is named after the monk Julianus. It must
not be confused with the Julian calendar system, which is named after
Julius Cesar, the Roman politician who introduced this calendar.
The Julian century is named after Cesar, i.e. a century in the Julian
calendar. The 'gregorian' century has a variable length.
Be aware the we always use astronomical year numbering for the years
before Christ, not the historical year numbering.
Astronomical years are done with negative numbers, historical
years with indicators BC or BCE (before common era).
Year 0 (astronomical) = 1 BC
year -1 (astronomical) = 2 BC
etc.
Original author: Marc Pottenger, Los Angeles.

(The parameter sequence m,d,y still indicates the US origin,
be careful because the similar function date_conversion() uses
other parameter sequence and also Astrodienst relative juldate.)

This function converts some date+time input {d,m,y,utime}
into the Julian day number tgmt, which is an Astrodienst relative
Julian date.
The function checks that the input is a legal combination
of dates; for illegal dates like 32 January 1993 it returns ERR
but still converts the date correctly, i.e. like 1 Feb 1993.
The function is usually used to convert user input of birth data
into the Julian day number. Illegal dates should be notified to the user.
Be aware the we always use astronomical year numbering for the years
before Christ, not the historical year numbering.
Astronomical years are done with negative numbers, historical
years with indicators BC or BCE (before common era).
Year 0 (astronomical) = 1 BC historical.
year -1 (astronomical) = 2 BC
etc.
Many users of Astro programs do not know about this difference.
Return: OK or ERR (for illegal date)
