  The Imperial calendar was based on a fixed 365 day year, each day
  being 24 hours.  Days were numbered 001-365, with no other
  official designations.  However, due to the length of time that a
  jump takes, widespread but informal usage of a "week" of seven
  days was common.  Normal notation is daynumber-year (for example,
  123-1201).

  The Solomani Confederation used Terra's old Gregorian calendar,
  and has done so for roughly the past 4,000 years.  This calendar
  is based on the cycle of Terra around Sol, and the day is based
  on the rotational period of Terra, almost exactly one standard
  day of 24 standard hours (there is speculation that this is in
  fact the origin of the Imperial calendar designation.  However,
  the current Imperial calendar is also a very close match for
  the day and year of Capital).  The year is divided into twelve
  approximately equal periods called "months" (with the number of
  days varying from 28 to 31 according to no discernible formula),
  and extra (intercalary) days are inserted approximately every
  four years according to a fairly complex formula.  Normal
  notation is name-of-month daynumber-in-month, year (for example,
  July 4, 5776).

  The Vilani calendar is based on the Vilani year of 500
  32-standard-hour days.  Each day consists of a "dran", or
  daylight period, and a "dir", or night period, each of 16 hours.
  Each dran and dir is numbered separately, yielding a total of
  1,000 distinct numbered entities over the course of the Vilani
  year.  Normal notation is year.dran-or-dir-number (for example,
  7453.293)

  Zhodani and Aslan also have their own calendars.  If you're
  interested, let me know, and I'll dig out that info and post it
  to the List.

  *Credit where due department:  Most of this information has been
  cribbed from GDW's own work, and also work by DGP.  The
  presentation here is totally my own, however.
