Cast a complete Qimen chart before interpretation
QimenMind is a browser-based San Yuan Qi Men Dun Jia calculator built around a chart-first workflow. Choose solar or lunar calendar input, enter a date and minute, and the free tool calculates the solar term, Yin or Yang Dun, Ju number, Xunshou, Zhifu, Zhishi, and all nine palaces without requiring an account.
The chart includes the Eight Gates, Nine Stars, Eight Spirits, Heaven and Earth Stems, Kongwang, Yima, Menpo, Rumu, Jixing, palace strength, and 81-pattern detection. Its San Yuan layer continues into Yuan Shen Gong, Yuan Qi Gong, Tian Yi Gong, Fei Fu, and Jin Tui. Each palace opens into a detail view that connects stem relationships and special states with the rest of the chart.
One explicit time basis and a reproducible link
Every manual chart is treated as China Standard Time, UTC+8. The current-time control also converts the current instant to Beijing time. QimenMind does not silently apply device time zone, geolocation, longitude, or true-solar-time adjustments, so users outside China need to convert the event time before entering it.
The share control puts the selected year, month, day, hour, and minute into the URL. Opening that link on another device recreates the same chart, which is useful for study, comparison, and follow-up discussion.
Optional AI reading stays on the locked chart
AI does not cast the chart. After calculation, a signed-in user can pass the same locked chart into an AI reading for useful-god selection, palace relationships, San Yuan movement, risks, and possible next actions. The first three AI questions are free per account; the site also lists short 1-day and 7-day access passes. The calculator itself remains free and available before login.
