Pillarwise
Your birth chart explained by astronomy, not fortune-telling
Free BaZi calculator with true solar time correction and explainable AI interpretation.
Most BaZi (Chinese birth-chart) calculators skip the one step that can change your result: true solar time. Clock time ≠ sun time, and the difference can shift your hour pillar — the foundation of an entire reading.
Pillarwise was built to fix this. Every chart is corrected to your birthplace's true solar time using historical timezone data, longitude, and the equation of time. Then the AI interpretation works like a coach — explaining what each pattern tends to mean in plain English, with the classical Chinese source quoted so you can verify the chain yourself.
We're not here to tell you your fate. We're here to give you a tool for self-reflection that doesn't hide its math.
Try the free calculator first — no sign-up, instant chart with the correction receipt shown.
