Chaldean order — the heptagram 7 = 7 = 7 (§15b.9, verified)
- (A) Sidereal periods, slow → fast: Saturn (29.46 a) > Jupiter (11.86) > Mars (1.88) > Sun (1.00) > Venus (0.615) > Mercury (0.241) > Moon (0.075). This is the Chaldean order — an astronomical fact.
- (B) Hourly week: 24 h/day, each hour ruled by the next planet in Chaldean order. The planet of the 1st hour names the day. 24 mod 7 = 3 → the next day jumps 3 planets.
- (C) Etymology: Tuesday = Mars/Martes, Wednesday = Mercury/Miércoles, Thursday = Jupiter/Jueves, Friday = Venus/Viernes, Saturday = Saturn/Sábado — the Romance names preserve the planet.
- The 7 doubles (ב ג ד כ פ ר ת) are the 7 planets; the 7 planets are the 7 days. The heptagram 7=7=7 closes by sidereal periods + mod-7 arithmetic + etymology. Note: the 7-day week is a cultural (Chaldean-Babylonian) artefact, not a continuous astronomical cycle; its astronomical anchor is the Chaldean order of the 7 planets, which is real.
The Chaldean heptagram — 7 planets in sidereal order on the ring; the gold {7/3} star traces weekday order (Sat→Sun→Mon→Tue→Wed→Thu→Fri), each day jumping 3 planets (24 h mod 7 = 3). 7 doubles = 7 planets = 7 days.
Each planet (a double) travels through the 12 signs (simples); that planet is read in a different sign depending on the day.
