Why the calculation matters
Plenty of sites say their math is right. But even with the eight characters right, the judgments built on them often slip: which character sits in which position, what each one is to you, how the Vital Element and the ten-year cycles are decided. A reading built on a wrong judgment reads just as smoothly, so the person reading it rarely notices.
- The eight characters themselves
- Birthplace, historical standard time and daylight saving, the selected time correction, and the exact solar-term moment can change a pillar.
- Strong or weak
- Counting characters alone often gives the opposite answer. The birth month weighs the most, and every position has its own weight.
- Ten-year cycles
- Forward or backward (year polarity and gender), the age they turn (days to the next solar term), and which cycle you are in now. Get one wrong and the whole sequence slides.
Get the math wrong and nothing else matters. Birthplace longitude, the standard time and daylight saving in force at birth, and the selected time correction can change the hour or day pillar. Even at the same clock time, you have to check which conditions were applied. AI gets this kind of math wrong all the time, and a reading built on the wrong chart still reads smoothly. Nobody notices.
How your chart is calculated
The year and month pillars change at the solar terms, not on January 1. The Hour Pillar uses the birthplace, historical standard time, daylight saving and selected time correction. Longitude correction leaves out the equation of time. You can choose from 479 cities around the world.
Do I need my exact birth time?
No. Tap "Time unknown" and the reading uses six of the eight characters. The Hour Pillar changes every two hours, so if you know the time, enter the hour and minute.
Your chart is right. We take your birth time to the minute and correct it for your birth city. The same birth details always give the same chart.
After the chart
Not a one-line horoscope. Your first reading is a long piece written on your own eight characters, Vital Element and ten-year cycles.
Ask as much as you like. Every answer stands on the same chart, so what she says later never contradicts what she said before.
