Chart calculator · Solar birth time
Calculate your Zi Wei Dou Shu chart.
Enter your birth date and time. The chart is computed in your browser using the iztro library; nothing leaves your device. The result places fourteen main stars and twelve palaces into the twelve cells dictated by your birth time — each cell links to its canonical glossary page so you can read the structure one room at a time.
What this chart is and isn't
The chart is descriptive, not prescriptive. It is a structural map of your default tendencies — where your energy lands, which life areas carry the strongest signature, which couplings the chart reads against each other. It is not a forecast: nothing here tells you what will happen, only what shape your operating system tends to take. A beta AI reading of your Life Palace now sits further down this page; beyond that, the cell labels link to the canonical palace and star pages, so you can read those one at a time and build out the rest yourself.
