A proposal to replace the Gregorian Calendar as the international standard.
The Gregorian Calendar, as a tool by which to measure and manage the passing of time, no longer serves the needs of the global community. Many alternatives have been proposed. This is another one. Details on each point to follow.
The Synaptic Calendar uses a thirteen month model as a basis. Thirteen months of twenty-eight days, each divided into four seven-day weeks. This adds up to three-hundred and sixty-four.
The remaining day and not-quite-a-quarter is observed off of the calendar, and falls between Saturday and Sunday, an intercalary day and not-quite-a-quarter.
Weekdays remain the same, with one significant change: Friday and Tuesday switch places, changing the order of the days to Sunday, Monday, Friday, Wednesday, Thursday, Tuesday, Saturday.
The thirteen months shall be numbered as the international standard, however, the names and symbolism for any given month is left to the discretion of the individual.
The thirteen months, plus the day and not-quite-a-quarter, should be delineated against constellations in the celestial sphere.
For the purposes of the calculation of longer spans of time, years shall be divided by magnitudes of twenty: 20 years, 400, 8000 160000, etc…
A chromatic counting of the days backwards and forwards will be used to synchronise historical accounts and other calendars as closely as can be done reliably.
A lunar calendar component will be added.
This particular proposal focuses on the seasons in the Northern Hemisphere. The Equatorial region between the two Tropics, and the Southern hemisphere will require special attention.
