Qi Men Hour Chart · what the moment favors.

Build a Qi Men Dun Jia chart for any moment — 9 palaces, 8 doors, 9 stars, 8 deities, and an auspice assessment for the current hour. Traditionally used for choosing when to negotiate, travel, relocate, or start a venture.

Computing your Qi Men hour chart…

How we compute this

◆ The method
Step 01

Resolve the solar term + yuan

Your local date + time + timezone is converted to the exact UTC instant, then to the Sun’s apparent ecliptic longitude. That longitude picks one of the 24 solar terms. The day’s position in the 60-day sexagenary cycle picks the Upper / Middle / Lower yuan.

local → UTC → solar longitude → 24 term · day index → yuan
Step 02

Select the Ju (formation) number

Each (solar term × yuan) pair maps to a specific Ju number 1–9. The Ju determines the initial stem placement on the 9 palaces and the polarity (Yang Dun before Summer Solstice, Yin Dun after Winter Solstice — stems fly forward in Yang and backward in Yin).

JU_TABLE[term][yuan] → Ju (1–9) · Yang / Yin Dun
Step 03

Fly the plate · assess the hour

The 9 QMDJ heavenly stems populate the Lo Shu 3×3 grid, then the Nine Stars, Eight Doors, and Eight Deities rotate around it based on the Duty Star’s hour position. Each palace returns an auspice (Greatly Auspicious → Greatly Inauspicious); the overall period is graded Favorable / Mixed / Unfavorable.

stems → palaces · stars + doors + deities rotate · auspice scores

Terms used on this page

Ju
“Formation” number (1–9) picked from the solar term + yuan pair. Determines initial stem placement on the 9 palaces.
Yang Dun / Yin Dun
Solar polarity — Yang from Winter Solstice to Summer Solstice, Yin the other half. Stems fly forward in Yang, backward in Yin.
Solar Term
One of 24 seasonal markers spaced 15° of solar longitude apart. Each term uses its own yuan sequence.
Yuan
Upper / Middle / Lower third of a solar term, indexed by the day’s position in the 60-day sexagenary cycle.
Duty Star
The star carrying the current hour. Its palace is the “active” palace; the offset from its home palace drives the rotation.
Three Wonders
The stems Yi (乙), Bing (丙), Ding (丁). Palaces containing them are generally favourable for starting activity.
Eight Doors
Kai · Xiu · Sheng · Shang · Du · Jing · Si · Jing. Each door has an intrinsic auspice that layers onto its palace.
Lo Shu
The 3×3 magic square that underpins all palace numbering: 4-9-2 / 3-5-7 / 8-1-6.
