Two classical chart systems without an account
Imperial Astrology puts Zi Wei Dou Shu and BaZi in separate free browser calculators. Both forms accept a Gregorian birth date, gender, and a two-hour birth period. An advanced panel adds an exact clock time and longitude, with presets for London, Paris, New York, Los Angeles, Sydney, Beijing, Shanghai, and Taipei. The site asks users to enter local clock time, then applies its longitude-based correction when precise input is enabled.
The Zi Wei Dou Shu result lays out all twelve palaces with Life and Body Palaces, Five Elements Bureau, major and auxiliary stars, Four Transformations, and decade ranges. The BaZi result shows the Four Pillars, Day Master, Na Yin, Ten Gods relationships, element balance, and eight luck-cycle steps.
Plain-English automatic readings are part of the free path
After a chart is calculated, a second free action generates an English reading. Zi Wei Dou Shu readings organize the result into a core portrait, a recurring pattern, and an energy map. BaZi readings continue through the Day Master portrait, strongest and weakest element themes, relationship and career notes, Ten Gods, and the current luck-cycle section. No account was requested during either tested calculator flow.
Public methodology, reference material, and human readings
The site includes a 107-star Zi Wei reference, articles, an editorial policy, privacy and disclaimer pages, and a public MIT-licensed Python chart engine. It says free readings are generated automatically, while paid reports are prepared by a human practitioner. Current one-time prices range from $24.99 for BaZi to $44.99 for the combined report, with separate season-pass subscriptions.
The calculators are new and should be treated as exploratory. In a January 1, 1990 functional check, the BaZi API returned a negative month in the luck-cycle start age and the automatic reading selected a mismatched current decade. Dates near solar-term boundaries deserve an independent chart check before relying on timing details.
