Corrections
What we got wrong, and when we fixed it.
写错了什么，什么时候改的。
Auspice is written and computed by one person, and one person gets things wrong. This page is the whole log — every factual, computational, or convention correction, with the original wording kept so you can see what changed. Nothing is quietly edited away.
What counts as a correction
- Factual — a quotation, dynasty, author, term attribution, or number that was wrong.
- Computational — a chart rule, true-solar-time conversion, or luck-cycle start that produced a wrong result. If your own chart is affected, we say so.
- Convention — we changed which school’s rule we follow. Not an error, but conclusions drawn from the old text may shift.
Typos, styling, and pure rewording are not logged — a correction log padded with typo fixes hides the real ones.
How a correction is handled
- The page is fixed, and the entry is added here with the original wording quoted.
- The page that was wrong shows the entry in its own footer — you do not have to come here to find it.
- That page’s dateModified moves to the correction date. Dates on this site only move when something actually changed.
- If you reported it, you are credited here unless you would rather not be.
Report an error
Email [email protected] with the page and what is wrong. A source helps but is not required — “this quotation isn’t in that book” is enough to make me go check. Replies come from the person who built this, within two business days.
Chart disputes are a different thing: the conventions we use are published at Method. A chart that differs from another site is usually a school difference, not a bug — but tell us anyway, and we will say which it is.
The log
2026-09-09 · Factual correction · /content/true-solar-time
Was: "Honestly: for most births, it doesn’t." — the true-solar-time correction rarely changes the hour pillar.
Now: It depends on where. A 40-city sweep of every clock minute across four reference years (scripts/solar-time-study.ts) finds the hour pillar changes for about 40% of minutes in the main overseas-Chinese cities and nearly half across mainland China (Shanghai 11%, Chengdu 58%, Kashgar 100%); only cities near their zone meridian, such as Taipei, fit "rarely". The old sentence generalised from one case; the page now gives the per-city numbers.
