LESSON P01 / 04 OF 20
Birth time and time zones
The hour changes one pillar. It does not change who you are.
Original app lesson · freely available here
Use the time zone of the birthplace, not where you live now.
What the hour actually decides
Birth time only sets the fourth pillar. Day Master, year and month are untouched, so the core reading survives an uncertain hour.
The hour pillar is usually read for later life, children and the private self. Supplementary, not structural.
Time zone is the usual mistake
A chart uses local time at the place of birth. Entering Taiwan time for a US birth can shift the whole Day Pillar — a different person.
That is why the settings ask for a birthplace. It matters far more than the exact minute.
What to do when unsure
Choose “unknown” rather than guessing. An invented hour makes you read something that is not there.
Check a birth certificate or ask family. Adding it later does not invalidate anything you have read.
The hour moves one pillar; the time zone can move the whole chart. Get the birthplace right first.
CHECK YOURSELF
Try the lesson questions
No score. An incorrect first answer enters your review book.
What should you avoid when the birth hour is unknown?
A guessed hour is fabricated data. Better one pillar short than one pillar wrong.
Why does the app ask for a birthplace?
A wrong time zone can push the date over a boundary, changing the Day Pillar and therefore the Day Master.
