The four daily hinges
Hinges are computed for your place in both modes: Yod at sunrise, Heh at solar noon, Vav at sunset, the final Heh at solar midnight. Times are shown in your place's clock time.
One Breath, All Ages
A prompt for every day of the Codex year, walking the path of Breath Awakens through the twelve chakras, thirteen places of stone and sky, and the ancient voices of the Earth.

Sky calendars of the world
Long before printed calendars, people read the year from stone and sky. The Codex stands in their lineage.
The Codex Global meridian. The pyramids face the four cardinal directions with remarkable precision.
At the equinoxes, late-afternoon light forms a serpent of triangles down El Castillo's staircase.
Its axis frames the midsummer sunrise and the midwinter sunset.
Twice a year, near 22 February and 22 October, sunrise reaches the statues deep inside the temple.
Ancestral Puebloan builders aligned walls and markers to the Sun, and perhaps to the Moon's long cycle.
The star cluster that opens the year from Aotearoa to the Andes, and shines in gold on the Nebra sky disc.
How the calendar works
The year begins at the spring equinox. Day 1 of Genesis Moon is the date on which the Sun crosses the equator northward, read at a reference meridian. Codex Global reads it at Giza (31.13° E) and gives everyone one shared date. Codex Local reads it at your own longitude; in a few years it starts a day apart from Global.
Thirteen Moons of 28 days. Every Moon is four weeks, and the Codex week resets on Day 1 of every Moon, so every date falls on the same day of the Codex week every year (the Gregorian weekday still shifts).
The Breath Day is a breath gap. It belongs to no Moon and no week. It is A'tharion-Keshariel, the still point between cycles. When the next equinox falls 366 days later, a Witness Day follows. Anyone keeping a Sabbath runs the global 7-day week in parallel, unbroken.
The 13-point wheel. Moons 1–11 carry the Egyptian archetypes from crown to feet, each at one of the twelve chakras of Breath Awakens; Moon 12 the Architect+, A'tharion-Keshariel, at the heart of the heart; Moon 13 Shekhinah, around the whole. The Breath Day returns to the still point, the 14th point, rebirth.
The true Moon rides on top. The 28-day Moons are a civil frame. Real phases are marked on each day, and each lunation is numbered in the 19-year Lunation Spiral of 235, which began with the New Moon of 19 March 2026.
Long cycles. Eight Solar Stations at every 45° of the Sun. Venus Breath: 8 years, in which 5 Venus cycles and 13 Venus orbits return together. Great Spiral: 144 years from 2026, in 4 Ages of 36 years and 12 Turns of 12.
