Suggestion: sign up with email or phone first, then link Apple / Google in settings. That way changing device or platform won't cost you the account.

2.2Birth details (the most important section in this guide)

Eighty percent of how accurate your chart is comes down to this.

About the hour

• –

  The hour determines the "hour pillar", one of the four pillars — missing it affects roughly a quarter of the reading

• –

  Not sure of the exact time? Pick the nearest period — "around three or four in the afternoon" → the hour of Shen

• –

  No idea at all? Choose "hour unknown". Most chapters are unaffected, and chapters sensitive to the hour are explicitly marked "accuracy limited"

About the place of birth

True solar time correction converts clock time into local solar time using the longitude of your birthplace. Fifteen minutes can change the hour pillar by a whole character, so fill it in if you can — city level is enough.

Born outside China (North America / Southeast Asia / Europe, etc.)

• –

  Enter the local date and time at your birthplace

• –

  Select the actual city you were born in

• –

  ⚠️ Do not convert the time to Beijing time. The system corrects automatically from "local time + birthplace longitude"; converting it yourself means the correction happens twice — and the chart is wrong

Wrong hour pillars are more common among overseas births than domestic ones. The reason is simple: a timezone difference often straddles exactly one two-hour period. If you were born in New York and entered Beijing time, the hour pillar is very likely already wrong.

Born in mainland China

The whole country keeps Beijing time, but the land spans five timezones. The actual solar time gap between Urumqi and Shanghai is close to two hours — the same "8 a.m." can fall into different periods in the two cities. So the birthplace is not optional.

Daylight saving time

Enter the time as it appeared on the clock, you don't need to subtract an hour. The system applies historical timezone rules automatically (the US, Europe and Australia have all used DST).

City not listed?

Pick the nearest city of the same level; the error is usually within one two-hour period. If your birthplace sits near a timezone border, prefer a city on the same longitude.

2.3Can I correct my birth details?

Advice: get it right the first time. Changing your birth date invalidates every report generated before.
