Clear Bazi Chart

Clear Bazi Chart is a free browser-based calculator for creating a Four Pillars chart from birth details. It presents the year, month, day and hour pillars alongside the Day Master, Five Elements, hidden stems, Ten Gods and luck cycles. The calculator runs on the user's device and does not require an account or a paid unlock.
Users can enter a Gregorian birth date or a Chinese lunar date and explicitly identify a lunar leap month. The supported Gregorian range is 1900 through 2100, including valid lunar dates that convert into that range. Birth time and sex can be entered with the date; sex is used for the traditional luck-cycle direction. When the birth time is unknown, an option leaves the Hour pillar out rather than inventing one. The other pillars and provisional luck onset use a noon reference, with additional boundary-sensitive possibilities checked across the civil day.
Time and location settings include an IANA time zone, editable longitude, an optional true solar time correction and a choice of day boundary. The browser's historical time-zone data resolves daylight saving time. For repeated daylight-saving hours, users can select the first or second occurrence. Nonexistent local times during a spring-forward transition are rejected. The calculation uses Li Chun for the year boundary and Jie solar terms for month boundaries.
The chart displays Five Elements counts separately from hidden stems. Its strength display follows a disclosed simplified scoring model; it is not presented as a consensus or an accuracy guarantee. The site describes its solar-time equation as an approximation and explains limitations near sensitive boundaries.
Results include expandable detail for Ten Gods, hidden stems, Na Yin, growth phases, voids, luck cycles and year-by-year pillars. Users can copy or print a result, or create a share link. The site explains that a share link contains the entered birth details in its URL fragment, so anyone receiving the link can read them.
The site also provides guides to chart reading and time settings, including worked examples about daylight saving and solar time. Its fixed-rule reflections are intended for exploration, not predictions. No AI is used for the reading. The calculation runs locally in the browser; the site says it does not upload or store birth details.
