The important takeaway is the emergence of many (maybe all?) values in time has a fractal (video) nature; each embodiment at every level resembles the others.
Supermillennium: many milleneums
Millennium: ~75% of a millenneum- a few milleneums
Submillenium: several centuries
Grand Supercycle: ~75% of a century- a few centuries
Supercycle: multi-decade
Cycle: 1-several years (possibly up to a couple decades)
Primary: a few months to a couple years
Intermediate: weeks to months
Minor: weeks
Minute: days
Minuette: hours
Subminuette: minutes
Micro: decades of seconds
Submicro: 1-several seconds
Miniscule: tenths of seconds
My understanding of the ranges are that the magnitudes roughly overlap, i.e. (0.75yr)-3 or 4 years could be a yearly cycle, likewise, a grand supercycle may last between 80-800 or 900 years. These are natural phenomena, which are modified by sometimes "infinite" variables. They have their own species.
It's definitely gray where the line is drawn for all systems, but usually one can figure out what a particular system is like for it's place in time.
There are an "infinite" amount of time scales, but I'm listing the most apparently relevant to humans currently.
I hope this is informational for you all! I love to use this figure alongside TA sometimes to help me forecast.
