出生 · BIRTH
A birth date is enough to start. Add your birth place and we'll build your chart.
Your birth place is only used for the true-solar-time (longitude) adjustment. A nearby big city is enough — it rarely changes your hour pillar. City data © GeoNames (CC BY 4.0)
The right choice for most people
Same as a normal calendar. Example: born 11:30 PM on March 5 → counted as March 5.
This decides which calendar day a birth belongs to if you were born between 11 PM and 1 AM. (Chinese/Korean astrology sometimes starts a new day at 11 PM instead of midnight.) Born at any other time? It changes nothing — just keep the default.
What you enter will be summarized here in one line.
