How it works
From birth details to a clear reading.
The calculator builds your Four Pillars chart first. Then a plain-English reading explains the Day Master, element balance, and timing themes— framed for reflection rather than prediction.
Birth detailsChartReadingEmail
Built around the chart, not vague prompts.
Birth date, time, and place create the Four Pillars structure. The reading then explains the Day Master, element balance, useful gods, decade luck, and current year themes in normal language.
Free chart first
Calculate a basic chart before deciding on a paid report. See your Day Master and pillars with no commitment.
Deeper report when ready
The upgrade adds more context, cleaner visuals, and a PDF you can keep—still framed for reflection, not guarantees.

FAQ
Questions people ask before they trust a BaZi calculator.
What is a BaZi chart?
A BaZi chart is a Chinese astrology birth chart made of four pillars (year, month, day, and hour), each pairing a heavenly stem with an earthly branch. The day stem is your Day Master.
Is this BaZi calculator free?
Yes. The online BaZi calculator shows your four pillars, Day Master, and five element balance for free. An optional paid PDF report adds more written context, framed for reflection rather than prediction.
What is BaZi?
BaZi, also called Four Pillars, is a Chinese metaphysics system that reads a birth chart through year, month, day, and hour pillars.
What is a Day Master?
The Day Master is the heavenly stem of the day pillar. Many BaZi readings use it as the starting point for interpretation.
Do I need my exact birth time?
Exact time helps because it affects the hour pillar. If you do not know it, you can still read the year, month, and day parts of the chart.
Is this fortune telling?
BaziCalc is for reflection and entertainment. It can suggest themes, but it should not replace professional advice or personal judgment.
Does time zone matter?
Yes. Time zone and daylight saving rules can shift the hour pillar, so enter your birth place and local clock time as accurately as you can.
What comes after the free chart?
The next useful layers are hidden stems, Ten Gods, luck pillars, and compatibility. Each has its own beginner guide on BaziCalc, so you can explore them at your own pace.
