 /**
  * Converts number of days since 24th November, 4714 B.C. (in the proleptic
  * Gregorian calendar, which is year -4713 using 'Astronomical' year
  * numbering) to Gregorian calendar date.
  *
  * Returned date belongs to the proleptic Gregorian calendar, using
  * 'Astronomical' year numbering.
  *
  * The algorithm is valid for all years (positive and negative), and
  * also for years preceding 4714 B.C. (i.e. for negative 'Julian Days'),
  * and so the only limitation is platform-dependent (for 32-bit systems
  * the maximum year would be something like about 1,465,190 A.D.).
  *
  * N.B. Monday, 24th November, 4714 B.C. is Julian Day '0'.
