Tenology 101 — the 585-day year, 18 uptops, and 220 days ahead

The plain-language explainer. Three numbers that hold the whole system together — and how they fit inside the 36-hour Tenology clock.

How the three numbers fit together

The Tenology time system is built on three numbers: a 585-day year, 18 uptops per cycle, and a 220-day lead over the Gregorian calendar. They are not independent — they are three views of the same underlying clock.

The year is 13 months of 45 days each. The day is 36 hours, twice the standard 18-hour half. Each hour is 18 uptops. So 18 uptops × 90 real seconds per uptop = one Tenology hour, and 36 hours close one Tenology day.

585-day cycle — the year

The Tenology year is 13 months × 45 days = 585 days. Same number is on the live calendar and in the manuscript. Every Gregorian calendar year, Tenology completes one full cycle and a 220-day head-start.

18 uptops per cycle — the clock

The 36-hour Tenology clock has a 5-number face. The orange hand ticks once per real second, holds steady on each of the 5 labels for 18 ticks (18 real seconds), then snaps to the next label.

220-day delta — the head-start

585 − 365 = 220 days. Each Tenology year closes 220 more days than the Gregorian year, so a Tenology user progresses 220 days further through their cycle per solar orbit.

The locked cadence — how the clock actually ticks

The Tenology clock has a 5-number face (labels 1 through 5). The orange hand moves one tick per real second. The hand dwells on each label for 18 ticks — that is 18 real seconds per label.

5 labels × 18 ticks per label = 90 ticks = one full rotation of the orange hand. One full rotation takes 90 real seconds, which is one Tenology uptop cycle.

18 uptop cycles make one Tenology hour. 18 Tenology hours make one half-day. 36 Tenology hours — two halves — make one full Tenology day.
