Well here goes... I hope people will help build this one up. It is the geometric calendar, the one clearly pointed to within the quran, for very good reason!
Define the terms as such:
1 year == 1 earth cycle (earth orbits sun 1x)
1 year = =12 lunar cycles (moon orbits earth 12x)
1 month == 1 lunar orbit
1 day == 1 earth axis rotation
Simple!
Now, there is something very special going on!
Yin, Yang
Sunrise, Sunset
Day, Night
Warm, Cool
Seasons:
Hot season (6 moon cycles)
Cold season (6 moon cycles)
Subdivide them:
Spring (3 moon cycles)
Summer
Autumn
Winter
Subdivide again! How do we do it this time?
Spring|Equinox|Summer|Solstice|Autumn|Equinox|Winter|Solstice
SpringRise SpringSet SummerRise SummerSet AutumnRise AutumnSet WinterRise WinterSet
You will notice, with Yin (coolness/stillness/ceasing) and Yang (heat/moving/energetic), there is a reversal:
Yin within Yang, Yang within Yin
(Yin within Yang) within Yang, (Yang within Yin) within Yin,
(Yang within Yin) within Yang and (Yin within Yang) within Yin
Each corresponds to a season
But we can go simpler: 2 seasons: hotter and colder, then into the Timeless Source (Tao/Spanda)
Or more complex: earth axis rotations PER lunar orbit PER solar orbit PER helic orbit PER galactic orbit PER orbit PER orbit PER orbit etc ad infinitenauseum
And also the other direction of complexity:
sunrise=>sunset; half-cycle between sunrise and sunset (morning), afternoon;
Cycle within morning: Early morning, Late Morning
Cycle within Early Morning: Early Early Morning, Late Late Morning
Essentially there is a way to subdivide somewhere along these lines such that we note the precise cyclical nature of every single day. There is a 'season' cycle in every day, and a kind of cycle within a cycle within a cycle.
This generates an absolute referential calender: a geometric calendar.
The problem with the modern calendar is the addition of a leap year. The attempt to impose a precise length on the year is laughable as The God has defined a year cyclically in the first place! The natural degree of variation and flexibility is what gives nature its greenness and lets rivers flow forth in abundance. When we impose rigidity on this by saying a year is 365.25393993 days long, we get the long straight roads, cities, grids, hives, dark concrete jungles and smog.
Let's see if some clever soul with imagination can find the cycle within a cycle within a cycle occuring day by day. The aim is to simply make a calendar, simply.
