Classical BaZi divides the day by the sun's position, not by administrative clock zones. BaZi Compass converts your birth clock time to true solar time using your birthplace longitude and the equation of time — the same standard used by serious practitioners. A birth at 12:00 in Ürümqi is a 9:50 solar-time birth: often a different hour pillar, sometimes a different day.

No third-party code runs in this app — no analytics, no advertising SDK, no tracking pixel. Don't take our word for it: open your browser's developer tools, watch the Network panel, and read your whole chart. Nothing leaves this site, apart from the licence check when you paste a key.
All calculations run on your device. Your birth data is stored only in this browser/app and is never uploaded, sold, or shared. Privacy policy · Terms
Everything stays on this device — no account, and no third-party code runs here to see it.
Don't know it? Pick Unknown.
Pick the sex recorded at the moment of your birth — that is what the classical method uses. It sets the direction your 10-year luck cycles (大运) run, from your birth-year stem plus one of two traditional rules the texts call 男命 and 女命. It is a calculation input from the tradition, not a question about who you are, and it changes nothing else in your chart.
☀️ All charts are cast in true solar time (真太阳时) — we correct your birth-place clock by longitude and the sun's real position before computing the pillars. Pick a city and even historical daylight-saving is recovered automatically for your birth date. Nothing to configure.
Hour unknown — we'll read your three known pillars (year, month and day). The reading is genuine but broader; the most precise reading needs the birth hour. You can add it later by editing this profile.

Checkout opens right here. Monthly or yearly — pick on the next screen.
How billing works: you subscribe on Gumroad and it renews itself — monthly or yearly, your choice at checkout. Your key keeps working for as long as the subscription is live, so there is never a key to re-enter. Cancel anytime from your Gumroad account: you keep everything through the end of the period you've already paid for, and you're never charged again.
Given a prepaid key instead (a gift, a promo, a one-off)? Those aren't subscriptions: a month key runs to the next major solar term (节) and a year key to Lichun (立春), then simply stops — nothing to cancel, nothing charged.
One key, your whole household: every pass (VIP 1 and VIP 2 alike) unlocks personal readings for every chart you keep — your parents, your partner, your closest family. Nothing is bound and nothing is counted: add a chart, correct a birth time or move to a new phone without spending anything. Free readings stay open for everyone, always.
🔒 Two gentle reminders: a birth chart is private — add loved ones with their blessing, and don't casually share anyone's full birth details. And your key is yours alone — it's what keeps your readings coming.
Beyond VIP: the Master Reading — $299, a complete written analysis of your entire chart — every pillar, every luck cycle, worked through in long form. Prepared for your chart by the same engine that powers this app, then read through and finalised by hand before it is sent (see the annual or More tab). Note: work begins as soon as payment is received, so orders can't be cancelled once underway; your statutory rights and the storefront's refund policy remain unaffected.
By subscribing or purchasing you confirm you have read and agree to our Terms of Use and Privacy Policy. Auto-renewing subscriptions continue until cancelled.
Keys are verified locally / with the store. No account needed. 💾 Save your key somewhere safe — screenshot it or keep the receipt. You'll need it again after a reinstall, or on a new phone. 🔑 Keep your key to yourself — it's yours, and it's what keeps your readings coming.
