BaziCalculator.ai asks for a Gregorian birth date, time, gender, and birth city. The selected city supplies a time zone and coordinates for true-solar-time correction before the Hour Pillar is chosen. If the birth time is unknown, the form can make an explicit three-pillar chart instead of inventing an hour.
The result keeps Heavenly Stems, Earthly Branches, hidden stems, Na Yin, growth stages, void branches, and Chinese Ten Gods on screen. Plain-English names such as The Challenger, The Creative Mind, and The Opportunity Magnet sit beside the traditional labels, so a new reader can follow the chart without losing the original terms.
The free result goes well beyond the eight birth characters. It shows a Day Master headline, dominant archetypes, destiny structure, favorable and risky elements, Five Elements percentages, notable stars, and the clashes and harmonies grouped under Life Dynamics.
The timing section lays out decade-by-decade Life Chapters, marks the current chapter, revisits earlier decades, and gives a short reading for each of the next five years. A public worked example shows the full sequence, including the clock-to-solar-time correction and a historical daylight-saving note for a 1990 Beijing chart.
The Four Pillars are produced by the site's rules engine. AI is used only when a deeper reading is requested. The free calculator needs no account and creates no saved AI-reading record, although the browser can remember the last-used inputs until they are cleared.
The privacy policy says account readings store validated birth parameters, the server-calculated chart, and generated text in a private Supabase record. The chart and limited timing context may be sent to DeepSeek for that optional reading. Shared chart links can include birth parameters, so they should not be treated as private. The same site also includes an English Bazi glossary, beginner guides, and a daily Huangli page with lunar date, ganzhi, solar terms, suitable activities, clashes, and directions.
