Flying Star Chart Calculator
This is the calculation a classical consultation is built on. Give it your home's facing direction (measured per our compass guide) and the year it was built or last fully renovated, and it casts the natal chart — all nine palaces, mountain and water stars, flown by the classical rules. We publish it because we'd rather show you the machinery than ask you to take it on faith.
Your natal chart
Where the timely stars landed
What this chart cannot tell you
Everything above is geometry. What it means depends on your floor plan — which rooms occupy which palaces, where the doors are, what the land outside each wall does. The same chart is excellent in one house and wasted in its neighbor. That mapping, palace by palace against your actual rooms, plus the annual overlay and your family's own charts, is what a residential audit delivers.
You've done the intake already
With your facing and period, the technical half of an audit's intake is complete. Send the chart link with your floor plan, and the master reads it against your actual rooms — report in 5–7 business days.

What the chart is
In Xuan Kong method, a building takes a fixed chart at construction: the period star of its 20-year era enters the center, and two further stars — the mountain star (people, health, relationships) and water star (activity, income) — fly through the nine palaces, forward or backward according to the polarity of the facing mountain. Nine palaces, three numbers each: the building's constitution for its lifetime, until a renovation deep enough to "change its breath" recasts it.
This is also why classical and template feng shui disagree: two homes a few degrees or a few years apart get different charts, and different advice.
