1. Year-Start Rule:
.
The calendar year starts with the Monday that starts nearest to the South-Solstice.
.
…or nearest to an approximation to the South-Solstice, based on the assumption that a South-Solstice occurs exactly every 365.2422 days. …starting from the actual South-Solstice of Gregorian 2017.
.
The approximation in the paragraph before this one is used by the main proposal for South-Solstice Equal 28-Day Months. Therefore that calendar’s year-start rule can be called an arithmetical year-start rule.
.
I call this the “South-Solstice Nearest-Monday year-start rule”.
.
Above I’ve defined two versions for that rule, an astronomical version and an arithmetical version. …and I specified that the arithmetical version is the one that I designate for my main proposal of South-Solstice Equal 28-Day Months.
.
2. Year-Division Structure:
.
The 13X28 year-division structure:
.
In a common year there are 13 equal months, each with 28 days.
.
Roughly every 5.6 years, on the average, the above-specified year-start rule will result in a year whose length is 53 weeks instead of 52 weeks.
.
In such a year, referred to as a “leapyear”, that extra, 53rd, week is added as part of the last month, which thereby becomes a 35-day month.
.
Naming of Months:
.
Not specified. But it is suggested that months be named by numbering. In particular, Esperanto numbering is suggested for month-naming:
.
Unua, Dua, Tria, Kvara, Kvina, Sesa, Sepa, Oka, Nua, Deka, DekUnua, DekDua, DekTria
.
<u><b>Designation of Day of the Month:</b></u>
.
Indicated by week-of-month and day-of-week.
.
Thus, today’s date, January 25th, is indicated by:
.
Month 2, Week 1, Friday.
.
This “week-&-day” format is due to Karl Palmen, who uses it in his Week & Month Calendar.
.
Michael Ossipoff
.
Month 2, Week 1, Friday (South-Solstice Equal 28-Day Months)
Dua, Week 1, Friday
5F (South-Solstice WeekDate)
(…meaning Friday of week 5)
January 25th (Roman-Gregorian Calendar)
