Short reference pages on how the four pillars are built and what the pieces mean. Everything here is free to read; the chart itself is free to cast.
What is a day master? — the single character a whole BaZi reading is built on, and all ten of them explained.
True solar time vs clock time — why the time on a birth certificate is not yet usable, and what changes when it is corrected.
The sixty day pillars — the full jiazi cycle, each with its classical character.
Cast your own chart — free True solar time, the full four pillars, and today's reading. No sign-up, nothing tracked, and your birth details never leave your device.For reference and reflection, a perspective from a classical Chinese tradition — never a guarantee, and never a substitute for professional advice.
