Period 8: Gēng sitting, Jiǎ facing
The natal chart
North-up. Each palace shows mountain star · water star with the base (period) star beneath; the facing and sitting palaces are marked.
Palace by palace
| Palace | Mountain ★ | Water ★ | Traditional note |
|---|---|---|---|
| E (facing) | 8 — White 8 | 8 — White 8 | The facing palace: water star 8 governs the traditional wealth reading here. |
| W (sitting) | 3 — Jade 3 | 4 — Green 4 | The sitting palace: mountain star 3 governs the traditional people-and-health reading here. |
| NW | 2 — Black 2 | 5 — Yellow 5 | The heaviest traditional affliction: illness and misfortune stars stacked. Kept still, clean, and metal-toned. |
| N | 6 — White 6 | 1 — White 1 | A settled pairing by traditional readings; suitable for active daily use. |
| NE | 4 — Green 4 | 3 — Jade 3 | Mixed pairing: Jade 3 is the untimely component; tradition avoids activating it. |
| Center | 1 — White 1 | 6 — White 6 | A settled pairing by traditional readings; suitable for active daily use. |
| SW | 7 — Red 7 | 9 — Purple 9 | Mixed pairing: Red 7 is the untimely component; tradition avoids activating it. |
| S | 5 — Yellow 5 | 2 — Black 2 | The heaviest traditional affliction: illness and misfortune stars stacked. Kept still, clean, and metal-toned. |
| SE | 9 — Purple 9 | 7 — Red 7 | Mixed pairing: Red 7 is the untimely component; tradition avoids activating it. |
How this chart was derived
- Period 8 enters the center and flies forward: the base layer.
- The base star at the facing palace (6) becomes the water star in the center, flying reverse per the Jiǎ mountain's polarity.
- The base star at the sitting palace (1) becomes the mountain star, by the same rule for Gēng.
This is the standard xia gua (下卦) method; facings within ~3° of a sector boundary invoke the substitute ti gua (替卦) method in some lineages, which this library does not yet cover. Which period a building belongs to (construction vs. move-in vs. gut renovation) is itself a school question — we note it rather than settle it. The annual stars for the current year overlay this chart; see Flying Stars 2026.
As with everything in this library: natal charts are a traditional system with no scientific support — the full picture is on our evidence page.
Frequently asked questions
What type of chart is the Period 8 Gēng-sitting, Jiǎ-facing home?
It is a Double Stars at the Facing (雙星到向) chart. Both timely stars gather at the facing. Tradition reads it as strong for wealth, weaker for health and relationships, and prescribes support at the back.
Which homes does this chart apply to?
Homes completed (by most schools' convention) during Period 8 — February 2004 – February 2024 — whose facing direction falls between 67.5°–82.5° on a compass, the Jiǎ (甲) mountain. Schools differ on whether construction, move-in, or major renovation sets the period, and facings within about 3 degrees of a sector boundary invoke the substitute (ti gua) method some lineages use. This page shows the standard xia gua chart.
How do I read the three numbers in each palace?
The large pair are the functional stars: the mountain star (left) governs the traditional people-and-health reading of the palace, the water star (right) the wealth reading. The small number is the base (period) star. In this chart, the timely star 8 appears as both stars at the facing palace.
