Thaat is a personality and strengths report calculated from your birth date using the Chinese calendar system (八字 BaZi). You get a free summary of your core element straight away, and the full report is a one-time unlock.

About the report

Yes. Your four pillars, your core element, the balance of the five elements, a short reading of your core element and a compatibility score with every reason are free, with no account. Only the full written report costs $9, paid once.

In BaZi (八字, Four Pillars), the day master is the heavenly stem of the day pillar, the day you were born. Thaat calls it your core element. It is one of ten: a Yang or Yin version of Wood, Fire, Earth, Metal or Water. It is not your Chinese zodiac animal, which comes from the year pillar.

Find your day master from a birth date

The day pillar gives one of ten core types: Yang Wood, Yin Wood, Yang Fire, Yin Fire, Yang Earth, Yin Earth, Yang Metal, Yin Metal, Yang Water, Yin Water.

All ten types in one table

Yes. Compare two birth dates and you get a score out of 100 with every reason behind it, free and for as many pairs as you like. The full report adds the written reading for each pair. The other person’s birth details are used only to calculate the comparison.

How the compatibility score works

No. The report describes personality tendencies and strengths from a traditional calendar framework. It does not say what will or will not happen to you, and it is meant for self-reflection and entertainment.

The element summary is free. The complete report is $9 USD, paid once by card. There is no subscription and no account to create. A refund within 7 days is available in the cases listed in the Terms of Service.

Practitioner consultations, AI subscriptions and one-time reports are different products and are priced very differently. Our pricing page lists named examples of each, with every price taken from the seller’s own page and dated.

BaZi reading prices compared

Your birth date, birth time (if you know it), birthplace and gender. The birthplace is used to correct your birth time to local solar time. Without a birth time the hour pillar is left out and the rest of the chart still works.

The year pillar changes at Lichun (3, 4 or 5 February) and the months at the solar terms, not on calendar dates. The day and hour pillars use true local solar time for your birthplace. The calendar is cross-checked against a separately written calendar library (sxtwl) on 2,233 test cases. The text you read is written in advance and assembled from your chart, with no AI text generation at the moment you press the button.

How a BaZi chart is calculated, step by step

Two different things. The calculation can be checked, and ours is tested case by case. Whether BaZi descriptions fit people better than chance has not been shown: we found one small study, with weak results, and no blinded, controlled test. Read it as a traditional framework for reflection, not as a measurement.

What can be checked and what the evidence shows

Birth details are kept only to produce your report and to restore it after you pay. You can delete your data at any time from the My account page. See the Privacy Policy for details.
