What time is each shichen?
The twelve traditional two-hour periods.
- Each period covers two hours; Zi crosses midnight.
- Ranges include the start, not the end: Chou starts at 01:00.
- This is a common modern clock-time reference, not a complete chart calculation.
Common modern clock-time reference
For a BaZi chart, also state whether clock or solar time is used, check historical time zones and daylight saving, and specify the day-boundary convention. Methods using 23:00 and 00:00 as the day boundary must be distinguished; this table does not choose one.
If this might help later, keep a copy of the card.
