Precision tools for better BaZi practice.
Use practical LearnBaZi tools to verify time, generate BaZi charts and support date-selection work with a clearer and more consistent workflow. Each tool serves a specific purpose: establish the calculation and context first, then apply judgement.
Three tools. One consistent foundation.
Each tool can be used independently, but they are designed to work together as part of a more disciplined BaZi workflow.
True Solar Time Calculator
Convert recorded civil-clock time into True Solar Time using the relevant historical UTC offset, longitude correction and Equation of Time. The calculator also supports reverse conversion for date-selection work.
- Historical civil-time and UTC-offset handling
- Longitude and Equation of Time correction
- True Solar Time and shichen conversion
- Clear handling of Zi-hour dates across midnight
- Date-selection conversion back to local civil-clock time
BaZi Chart Generator
Generate a structured BaZi chart with True Solar Time integrated into the charting process, giving students and practitioners a clearer foundation for natal analysis, Luck Pillars and timing work.
- Four Pillars chart generation
- Integrated True Solar Time calculation
- Current and selectable Luck Pillars
- Annual and monthly timing views
- Designed for desktop, tablet and mobile use
Day Selection Calendar
Assess potential dates and hours for planning and action using the LearnBaZi Day Selection methodology. Review the calendar in your selected location and use the results alongside the purpose and context of your plans.
- Calendar and Best Upcoming Days views
- Daily ratings and individual-hour details
- Output and Resource filters
- Location-based local dates and times
- Compare dates before reviewing individual hours
Good interpretation starts with good calculation.
A BaZi reading is only as reliable as the inputs used to construct the chart. Time-zone history, solar correction and chart conventions can materially affect the hour pillar and downstream analysis. LearnBaZi tools are built to make those calculation steps visible rather than hiding them behind a single result.
LearnBaZi principle: calculate first, verify second, interpret third. The purpose of these tools is not to replace judgement, but to give students and practitioners a more consistent technical foundation for that judgement.
More LearnBaZi tools are coming.
This page will remain the central access point for future LearnBaZi calculators, assessment tools and practitioner references. As new tools are released, they can be added here without changing the overall workflow.
Start with the right calculation.
Use the True Solar Time Calculator first when birth or event time requires verification, then generate a BaZi chart or assess dates and hours with the Day Selection Calendar.
