Ziwei Home is a Simplified and Traditional Chinese Zi Wei Dou Shu chart site. Its birth form accepts a date in the Gregorian or lunar calendar, a clock time or traditional two-hour birth period, a birthplace city and gender. The chart method accounts for birthplace longitude, historical daylight saving time and a 23:00 day change. If the birth hour is uncertain, the site describes a way to compare nearby hour charts rather than treating the time as settled.
A free chart sits alongside reference pages for all twelve palaces, fourteen major stars and sixteen smaller stars. The brightness table places fourteen major stars across twelve palaces. Its notes compare all 168 positions with passages in Zi Wei Dou Shu Quan Shu: 151 match, fourteen differ and three have no grade in the cited passage. Readers can therefore see where the site's chart rules follow or depart from that classic.
Basic charting and the reference library are available without signing in. Full twelve-palace written reports, questions about a chart, compatibility and date selection are offered through subscriptions or credits. The site's FAQ says an unclaimed chart made without an account remains on its server for seven days, then is deleted if it has not been reopened. The birth-data handling is worth reading before entering another person's details.
