Bazi & Saju Calculator: Jiazi

Natal chart Calculator and Analysis, Compatibility and Daily Astrology

Generate your bazi chart from your birth date, time, and place - and read what it actually means. Jiazi calculates your four pillars of destiny, picks out your day master, and breaks down your five elements without the jargon.

Daily readings show how today's energy meets your chart. Monthly and yearly readings zoom out for planning.

YOUR CHART

The four pillars (year, month, day, hour), heavenly stems, earthly branches, hidden stems, and ten gods - laid out cleanly so you can read your own bazi chart instead of paying for a one-time bazi reading.

DAY MASTER ANALYSIS

Your day master tells you how you think, lead, and rest. Jiazi shows yours, the elements that support it, and the ones that drain it.

FIVE ELEMENTS BALANCE

See where your chart is heavy and where it's thin. Wood, fire, earth, metal, water - and what to do with the imbalance.

DAILY, MONTHLY, YEARLY READINGS

Open the app and see today's pillar against yours. Useful for timing decisions, noticing patterns, or just paying attention to the day.

Monthly readings cover the cycle ahead. Yearly readings cover the year's pillar - what it asks of you and where the friction shows up. It's daily chinese astrology grounded in your own chart, not a sun-sign horoscope.

COMPATIBILITY

Add a second chart and Jiazi compares the two. The bazi compatibility reading covers element interactions, day master dynamics, and the friction or support between the pillars. Pick the relationship type (romantic, family, friendship, work) so the reading frames itself the right way.

SAJU SUPPORT

Bazi is called saju in Korean - same system, same pillars. Jiazi works as a saju calculator and as a bazi app, with the UI fully translated into Korean. The saju chart, saju reading, and bazi reading are the same calculation under different names. If you're more familiar with korean astrology than the Chinese terminology, the math is identical.

MULTIPLE PROFILES

Free with one profile. Premium adds unlimited profiles - save your partner, your kids, your parents - and switch between them in one tap. Notes attach to each profile.

WHO IT'S FOR

People learning chinese astrology and wanting a working bazi chart calculator instead of a static lookup. Long-time readers who want their bazi reading on hand. People curious about the four pillars who just want a clean way to read their own chart.

A natal chart in the chinese astrology chart tradition - a chinese birth chart, a saju chart, and a complete bazi reading in one app. Beginners can stick to the plain-English summaries; if you go deeper, the bazi chart analysis covers ten gods, hidden stems, and bazi chart interpretation in detail. Bazi personality readings come from your day master and pillar combinations.

NATAL CHART CALCULATOR
