The day star turns over once a day, the hour star every two hours. Wherever the two land, that corner of the house leans auspicious or quiet at this moment. This page works out true solar time for your longitude, casts both charts, and says plainly which of the eight directions to use right now and for what. It holds for this hour only — long-term layout belongs to the house chart and the landform, which is a different job.

East is positive, west negative. Leave blank to use the selected city.

The eight directions, right now

South at the top, as on a compass. In each palace the day star sits above the hour star: the hour star rules this moment, the day star sets the tone of the day.

This is now — not the whole day

This chart follows the hour star: it shows the dos and don’ts of this two-hour period only, not of the whole day. For the directions to use later this morning, this afternoon or tonight, see Today, direction by direction below.

Today, direction by direction🔒 Your day, in plain words

This section is about today; the chart above is about right now — two different questions. The day star holds all day and sets each direction’s tone; the hour star turns every two hours and lets you pick a better moment inside that tone. A direction that is poor at this moment is not poor all day: usually the hour star is only weighing on it, and the hour will turn.

What to do with each direction today

Day chart sets the tone, hour chart finds the window — folded into one plain sentence: which direction works today, which to avoid, and if you truly cannot avoid it, what hour to push the task to.

The twelve hours of today🔒 Full day

The day chart holds all day; only the hour star moves. Find the hour you plan to act in, then read which direction to use and which to leave alone.

🔒

All twelve hours at a glance

The chart for right now is free in full. To lay out the auspicious direction for every remaining hour of today — when to book that meeting, which hours to keep quiet — you need an active membership.

How to read this

  1. Fix the centre first — the geometric centre of the whole home, or of the room in single-room mode. Move the centre and every direction moves with it.
  2. Then find the directions: "South" on the board is magnetic south. Stand (or sit) at the centre; whichever way you face is the direction you are using.
  3. An auspicious direction is for doing, not for occupying. Reading, negotiating, deciding — move there for the task; sitting there all day adds nothing.
  4. A "keep quiet" direction is not a bad place, only one you need not disturb right now. No hammering, no heavy moving, no digging — ordinary living is fine.

Where the rules come from

The day and hour stars both belong to the "visiting star" layer of Xuan Kong; the rules are below. Solstices are taken at their true astronomical moments, not approximated as 21 December or 21 June — a day of error at the boundary shifts the whole chart by one palace.

Day star: forward after the winter solstice, backward after the summer. Our own rule set and the "modern" one anchor on the first Jia-Zi day after the summer solstice and start from 9 Purple; the "strict classical" set follows the three-fold division recorded in Xuan Ze Qiu Zhen — 9 Purple at the summer solstice, 3 Green at End of Heat, 6 White at Frost Descent — each anchored on the Jia-Zi day nearest its boundary.
Hour star: on Zi, Wu, Mao and You days the Zi hour starts at 1 White, on Chen, Xu, Chou and Wei days at 4 Green, on Yin, Shen, Si and Hai days at 7 Red — forward after the winter solstice, backward after the summer. Only the starting star after the summer solstice differs between schools (below).

One thing worth stating plainly: the day and hour stars are guests — they only add to or subtract from the moment. The house chart is the host, and it sets the tone for decades. A guest cannot overrule the host: an auspicious direction will not turn a structurally poor house into a good one, nor will a quiet direction ruin a sound one. Use this page to choose between options, not to pass verdicts.

Which rule set this page uses

Currently using Our default. Switch "Rule set" above to use another; the nine palaces and the twelve-hour table are recast together.

Our default
Our default. The day star uses only the two solstices: after the summer solstice it anchors on the first Jia-Zi day, starts at 9 Purple and flies backward until the winter solstice. Hour stars after the summer solstice follow the second textual tradition: 9 Purple on the four cardinal-branch days, 6 Green on the four tomb-branch days, 3 Green on the four growth-branch days, all flying backward.
Strict classical
Following Xuan Ze Qiu Zhen (vol. 7) and Xuan Ze Ji Yao. The day star uses six spans (winter solstice, Rain Water, Grain Rain, summer solstice, End of Heat, Frost Descent); the yin period divides threefold — 9 Purple from the summer solstice, 3 Green from End of Heat, 6 White from Frost Descent — each anchored on the Jia-Zi day nearest its boundary, flying backward. Hour stars follow the first textual tradition: 3 Green on the four tomb-branch days, 6 White on the four growth-branch days (exactly swapped against the second tradition).
Modern common
The practice of most contemporary charting tools: same anchor as our default, but after the summer solstice the flight stays forward instead of reversing (in effect carrying 9 Purple onward). Hour stars follow the second tradition.

Where the disagreement comes from. For the day star, Xuan Ze Qiu Zhen records "…after the yin begins at the summer solstice the nine palaces reverse; three Green at End of Heat, six White from Frost Descent". For the hour star two readings circulated — "6 White for the growth days, 3 added for the tomb days" against "3 Green for the growth days, six added for the tomb days" — and Qing scholars already wrote on the point. This page sets the three side by side and does not rank them; the chart follows your choice. One note: the hour-star rules here have been corrected to the texts above, so results may differ from older tools.
