243 ** Based on formulae originally posted by

246 ** Reposted 14 May 1991 in FidoNet C Echo conference by
247 ** Paul Schlyter (Stockholm)
248 ** Minor corrections, added JDN to julian, and recast into C by
249 ** Raymond Gardner Englewood, Colorado

251 ** Synopsis:
252 ** long ymd_to_jdn(int year, int month, int day, int julian_flag)
253 ** void jdn_to_ymd(long jdn, int *year, int *month, int *day,
254 ** int julian_flag)
255 ** year is negative if BC
256 ** if julian_flag is > 0, use Julian calendar
257 ** if julian_flag is == 0, use Gregorian calendar
258 ** if julian_flag is < 0, routines decide based on date
259 **
260 ** These routines convert Gregorian and Julian calendar dates to and
261 ** from Julian Day Numbers. Julian Day Numbers (JDN) are used by
262 ** astronomers as a date/time measure independent of calendars and
263 ** convenient for computing the elapsed time between dates. The JDN
264 ** for any date/time is the number of days (including fractional
265 ** days) elapsed since noon, 1 Jan 4713 BC. Julian Day Numbers were
266 ** originated by Joseph Scaliger in 1582 and named after his father
267 ** Julius, not after Julius Caesar. They are not related to the
268 ** Julian calendar.
269 **
270 ** For dates from 1 Jan 4713 BC thru 12 Dec Feb 32766 AD, ymd_to_jdn()
271 ** will give the JDN for noon on that date. jdn_to_ymd() will compute
272 ** the year, month, and day from the JDN. Years BC are given (and
273 ** returned) as negative numbers. Note that there is no year 0 BC;
274 ** the day before 1 Jan 1 AD is 31 Dec 1 BC. Note also that 1 BC,
275 ** 5 BC, etc. are leap years.
276 **
277 ** Pope Gregory XIII decreed that the Julian calendar would end on
278 ** 4 Oct 1582 AD and that the next day would be 15 Oct 1582 in the
279 ** Gregorian Calendar. The only other change is that centesimal
280 ** years (years ending in 00) would no longer be leap years
281 ** unless divisible by 400. Britain and its possessions and
282 ** colonies continued to use the Julian calendar up until 2 Sep
283 ** 1752, when the next day became 14 Sep 1752 in the Gregorian
284 ** Calendar. These routines can be compiled to use either
285 ** convention. By default, the British convention will be used.
286 ** Simply #define PAPAL to use Pope Gregory's convention.
287 **
288 ** Each routine takes, as its last argument, a flag to indicate
289 ** whether to use the Julian or Gregorian calendar convention. If
290 ** this flag is negative, the routines decide based on the date
291 ** itself, using the changeover date described in the preceding
292 ** paragraph. If the flag is zero, Gregorian conventions will be used,
293 ** and if the flag is positive, Julian conventions will be used.
