Zi Wei Dou Shu arranges a birth moment into twelve palaces. Time matters, so this flow gives alternatives when your recollection is approximate and stops when it is unknown.

Date of birth

Time of birth

I know it I know roughly when I have no idea

The two-hour period you were born in decides the Life palace, and everything else is built on that. It is the one thing this cannot guess for you.

Time zone of your birthplace

This starts on the zone your device is in now. If you were born somewhere else, change it — the zone decides the hour, and the hour decides the chart.

Longitude of your birthplace

Filled in from the zone’s main city. Your own town’s longitude is better if you know it: the chart is drawn in local solar time, and 15° is one hour.

Your free chart and answers stay in your browser. This free experience calculates on your own device without sending your birth details or individual answers. No account, email or payment is needed. Close the tab to discard this page’s inputs.
If you later choose the Personal Pattern Report, a separate checkout preparation sends only the completed chart and six aggregate scores to PracticeEco. They are encrypted and held for up to two hours while you review the order; the original 24 answers and birth fields are not sent.
This experience sets no analytics cookie and sends no form activity to a third-party tracker. Only coarse, first-party event names are counted; they never include what you typed.
