More complete specific definition

 For the Subjective Seasonal Calendar, the months have the lengths that I specified in my earlier postings, except that, for the nonfixed version, I"d previously made a 1-day error, which I correct here:
 
(season names refer to Northern Hemisphere--for international use, numbers or letters would be substituted)
 
Nonfixed:
 
Summer & winter: 117 days
Spring: 65 days
Autumn: 66 days
 
Fixed:
 
Summer & Winter: 17 weeks
Spring & Autumn: 9 weeks
 
By definition, June 1 is the first day of calendric summer.
 
But that needs more specificness:
 
If we keep the Gregorian leapyear system:
 
Then continue using it without any interruption or change. In the first year of the new calendar's use, the first day of the Summer calendric season is June 1. Then, using the Gregorian leapyear system, let things fall where they may.
 
If we don't keep the Gregorian leapyear system:
 
Apply a leapday or (for the fixed version) a leapweek at such times so as to minimize the maximum drift in the tropical year, as measured by the Sun's ecliptic longitude, of noon GMT on the first day of calendar Summer, away from the Sun's ecliptic longitude that was the middle of the cyclical drift of noon GMT, June 1, for the 2004-2008 leapyear cycle, in our current Roman/Gregorian calendar.
