What makes 星と暦の占い different

  1. 1

    Not just side by side—one answer

    Most fortune sites simply list each method's result. 星と暦の占い puts the conclusions of five methods on the same scale and, built around where they overlap, brings them together into one answer for you. Where they disagree, we tell you honestly with a "however".

  2. 2

    Judged by the classics, not written by AI

    AI does not write a new text each time. We calculate according to judgment rules drawn from classics such as the Di Tian Sui, Qiong Tong Bao Jian and Zi Wei Dou Shu Quan Shu. The same birth date always gives the same answer.

  3. 3

    The moment of birth, precisely

    We calculate the time difference from your birthplace's longitude and the exact moments of Risshun and each solar term. Even if you were born in January, February or at a change of season, the calendar boundaries are never mixed up.

How we calculate, and our sources

We studied and catalogued 1,000 sources, including divination texts and research, and checked 12 classics against their original texts. The breakdown by method is as follows.

Four Pillars / BaZi127Di Tian Sui, Qiong Tong Bao Jian, Yuan Hai Zi Ping, San Ming Tong Hui
Western astrology291Ptolemy's Tetrabiblos, Sepharial and others
Zi Wei Dou Shu25Zi Wei Dou Shu Quan Shu
Nine Star Ki71Shuo Gua Zhuan, Xie Ji Bian Fang Shu and others
Sukuyo astrology106Xiuyao Jing (Sutra of the Lunar Mansions)
Numerology, tarot and others380Cheiro, Waite, I Ching studies and more

We convert your birth date and time into true solar time at your birthplace, divide years and months at the exact moments of Risshun and the solar terms, and then calculate. Each method's conclusion is restated as a "theme" and a "momentum", overlaid, and the text is built around what overlaps most. AI does not write a new text for each reading.

Frequently asked questions

Can you really read my fortune from just my birth date?

Yes. Four Pillars, Nine Star Ki, numerology and Western astrology can all produce a basic chart from your birth date alone. If you know your birth time and place, we correct for true solar time and read in detail, down to the houses of your horoscope and the hour pillar of Four Pillars.

Is it free? Do I need to sign up?

Everything is free, with no membership or email address required. Your birth date is calculated only on your own device and never sent to our server.

If different methods give different results, which should I believe?

Rather than just listing the conclusions of five methods side by side, 星と暦の占い weighs them and combines them into one judgment. Where the methods disagree, we tell you that honestly too.

Can I see my fortune for today, this month and this year?

Yes. Choose "Today", "Tomorrow", "This month" or "This year" before your reading, and we combine the flow of that period and tell you concretely, down to your tailwind days and the times to be careful.

Is it accurate?

Fortune-telling doesn't fix your future. We researched about 1,000 classics and specialist books and calculate charts faithfully by traditional methods. Please use the results as hints for looking at yourself again and thinking about your next step.
