- The date reference on this record’s page includes wording that is not in the cited text (開皇). That wording is this project’s reckoning or note.
- Read through an AI working translation.
- Region
- East Asia
- Theme
- Economy and exchange
- 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
- Sui 開皇7年, fourth lunar month
- 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
Read zztj176.wikitext lines 165–195: the explicit fourth-month heading follows the second-month material and precedes the fifth-month heading at line 191. Read lines 30–34 of sinica-586-12-31.html and sinica-587-12-31.html: Julian 586-12-31 is Sui 開皇6年丙午11月15日; Julian 587-12-31 is Sui 開皇7年丁未11月26日. Sui's intervening fourth month falls in Julian AD 587, matching the annal's 丁未 year.
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.
