Simsaju combines solar-term, true-solar-time and daylight-saving calculations with hidden stems, Nayin, strength, chart patterns and favorable elements. Its Saju engine provides fifteen report types and question-based chat, with editable hour pillars and saved chart images.
True solar time uses city-specific adjustments and worldwide daylight-saving support. Charts expose Nayin, hidden stems, strength, pattern changes and the three-useful-gods system.
Expand major periods into annual and monthly periods and switch pillar order, scripts and widgets.
