It's built on Purple Star Astrology (Zi Wei Dou Shu), a thousand-year-old Chinese method for mapping personality and the timing of a life. You don't need to know anything about it, or take anything on faith — check it against your own past first, and judge for yourself.

How is this different from a personality test like Myers-Briggs or the Enneagram?

Those ask you questions and sort you into a fixed type — they can only reflect what you told them. This asks nothing: it's drawn from the exact moment you were born, covers all twelve areas of your life, and tracks how each one changes over the years. No two readings are alike.

Is this a subscription?

No. The reading is a one-time $19.90 — not a subscription, and yours to keep. (Your Purple Pal is a separate, optional $3.99/mo, free for the first four weeks.)

What if I don't know my birth time?

Noon is a usable default for the chart; precision improves with the exact time. We'll tell you which parts of the reading are affected.

Can I compare my chart with my partner's?

Yes. Invite anyone with a private link — they create their own chart, and you both see how the two of you cross, plus a written reading of the pair. Comparing is part of Your Purple Pal, free for your first four weeks with the full reading.

Will you sell my data?

No. Birth data is encrypted and used only to generate your chart. We don't share it, sell it, or use it for ads. Your public link is off by default and hidden from search engines.

What if I hate the reading?

Email us within 30 days for a full refund. No questions asked.

Why $19.90 and not free?

Generating each personalised reading costs us real compute and writing time. $19.90 covers it and lets us keep the free tier genuinely substantial for everyone.

How a Zi Wei Dou Shu reading works

Last updated · June 16, 2026

From the moment you were born to a reading of your character and the timing of your life — here is exactly how a Zi Wei Dou Shu reading (Purple Star astrology) is built, in five steps.

The short answer

A Purple Star reading turns one piece of information — the exact moment you were born — into a map of twelve areas of your life and how each one moves through the decades. The maths is done for you. What you read is language about your actual life: who you are, where you have been, and the years ahead.

Step 1: Give your birth moment

You enter your birth date, time, and place. The time matters most — it's what makes the chart yours rather than a whole day's. If you don't know it, noon is a workable stand-in, and the reading flags which parts lean on the missing detail.

Step 2: Your chart is cast for that exact instant

Your birth time is corrected to true solar time — the sky exactly as it stood above your birthplace, not clock time. From that instant the chart is drawn: the still centre, and the bodies arranged around it.

Step 3: Twelve areas of life are mapped

The chart is divided into twelve areas — self, money, career, love, children and creativity, health, travel, friends, allies, home and family, the inner life, and the people who shaped you. Each one is read from where its stars fall.

Step 4: The reading follows each area across time

This is the part Western astrology rarely reaches: each area is tracked decade by decade and across the year ahead. The reading shows the chapter you're in now, the ones behind you, and which years ask the most of you — and which give back.

Step 5: You read it in plain, warm language

Your opening portrait and four of your twelve areas are free — written as language about your actual life, never charts or symbols. The full reading is a one-time $19.90 with lifetime access, and includes a four-week trial of Your Purple Pal.

How long does it take?

A few minutes. You enter your birth details, and your free reading appears straight away — the portrait and four of your twelve areas. If you unlock the full reading, the remaining areas, your decade-by-decade archive, and your year month by month are written for you in moments.

Do I need to understand astrology?

No. You never see charts, symbols, or Chinese terms — only warm, readable language about your life. The honest test isn't belief; it's memory. The reading describes where you have already been as precisely as where you are going, so you can check it against your own past first.

Start your own reading

The best way to understand the steps is to walk them. Your opening portrait and four areas are free — no card, nothing to fill in but the moment you were born.
