- Kind of record
- Placed in a year. A source places this in one year. It is listed under that year; no day precision is invented.
How it is dated
- Date reference
- Taihe 3, ninth lunar month; Wu Huanglong 1
- How we use it
- Year-level placement is limited to the dated source entry.
The date reference is this project’s reading of the source’s date. It may give an era name, a reign or a calendar in a normalised form rather than in the source’s own words; the dating notes say what the source prints.
Dating notes from the research record
zztj071.wikitext row 71 identifies Taihe 3 as 己酉, AD 229; row 75 records Wu's change to Huanglong. Examined sinica-229-01-08.html and sinica-229-12-27.html, rows 31–32 and 34–66: January 8 is 戊申 month 11 day 26; December 27 is 己酉 month 11 day 24 for Wei Taihe 3 and Shu Jianxing 7, but day 25 for Wu Huanglong 1. That court-specific one-day difference does not affect the ninth month's assignment to civil AD 229. Original quotation begins at line 89, character 5851.
File names and line numbers in these notes, and in the limits above, refer to the project’s retained copies of the cited sources. Names such as calendar_headers are the project’s calendar look-ups, and “the investigator” is the research step that prepared the record.
