2019-08-06 - Reformed Rational Calendar
 ---------------------------------------
 
 Introduction
 
 Problems with systematic calendars (syscals)
 
 Triskadekaphobia
 
   Many syscals provide 13 months. This is unpopular for many
   reasons. You can argue against this objection all you want, the
   fact remains that, in many cultures, 13 is unacceptable.
 
 Unfamiliar Days
 
   Many syscals provide new day names, such as the French Republican
   Calendars unidi, duodi &c. These have a certain attraction, but
   they are not without problems, mainly the erosion of cultural
   reference points.
 
 Loss of Weekends
 
   Syscals which excessively focus on rationality (FRC, New
   Calendar) reduce the `rest days`. This was one of the
   contributing reasons for the failure of the French Republican
   Calendar.
 
 Unfamiliar Terminology
 
   Many syscals refer to incongruous naming schemes, like `bimonth`.
 
 Loss of Holidays
 
   Many syscals overturn or move traditional holidays (Thanksgiving
   &c). People *really* like their holidays; many of them have been
   obtained through the force of organised labour; others
   commemorate the deeds of the past and are part of national,
   regional and supra-national identity.
 
 Loss of Productivity
 
   Conversely to the above, some syscals actually increase the
   number of days people are not working. This leads to strong
   objections from the Capitalist classes; until such time as these
   objections can be rejected there needs to be some consistency.
 
 Loss of Traditional Measure
 
   By altering week length, or dividing months differently, many
   religious or traditional elements are lost or become overly
   complex. A new calendar should not minimise impact on these old
   calculations.
 
 
 Problems with Julian/Gregorian System
 
 I'm not proposing to delve too deeply into the problems with the
 current system. Anyone who has any interest in Calendrical Reform
 knows these issues. To keep it short, there are three primary
 complaints, viz:-
 
  - Unequal Months
  - Shifting Days
  - Overly Rigid
 
 So, what should a reformed Calendar do?
 
 In order to minimise friction, a reformed calendar should:-
 
   Retain month structure as much as possible 
   Retain local naming conventions 
   Retain Holidays
   Retain Weekends 
   Retain Productivity 
   Retain Traditional Measures 
   Retain 7 Day Week
 
 My Modest Proposal
 
 Use ancient structure for new
 
   A Reformed Calendar should look to the original calendars used
   by humans. Many early cultures, and their descendants today,
   concentrate on the Solstices.
   
   A Reformed Calendar should acknowledge the Holiday 'seasons'
   which occur at Solstice
 
 
 12 Months of 28 Days
 
   Beginning on Jan 1, each month is the same length. 
   Each Month (or Month Ordinary) retains its traditional local name 
   Each day retains its traditional local name 
   Each traditional local holiday remains largely in place, with
   some exceptions.
 
 
 Plus: 2 Half-Months of 14 Days
 
   Located after June and after December 
   Coterminous with Midsummer and Midwinter Solstices
 
 Kalends Days
 
   One *Kalends* at the end of each year, after the Winter(NH),
   before the start of the new year.
 
   One *Ides* every four years, after the Summer(NH)
 
 
 Issues
 
 Doesn't work for other religions
 
   Judaism (for instance) relies on a 7-day week, and does not allow
   `intercalenary` days.
 
 
 Birthdays
 
   Because the calendar is quite different, birth dates from the
   Gregorian calendar do not neatly align. This can be assuaged
   somewhat by taking the absolute year-day, and mapping this to the
   new calendar.
