General suitability
Public pages describe patterns for everyone using one stable timezone. They do not know your birth details, location or priorities.
Learn the reference
Tong Shu is a calendar of traditional signals, not a promise.
Tong Shu—also called a Chinese Almanac or Huang Li in different contexts—organises date-based markers such as Day Officers, activity suitability and reference hours. People use it as one planning input alongside practical evidence.
How to read a public date
- Start with the date, reference timezone and method version.
- Read the Day Pillar and Day Officer as general context.
- Compare suitable and avoid activity markers with real constraints.
- Use the reference hours as a prompt, not as a guarantee.
Personal suitability
A private guide can compare approved personal inputs with the same general facts. That result remains authenticated and non-indexable.
Next step
Read a date, then explore the assumptions before deciding whether a private preview is useful.
