Sources with scope,
not authority by association.

Every source on this page is attached to a specific use. A calendar table can support a conversion reference; it does not validate a later interpretation of a symbolic reading.

Summary

Sources are listed with publisher, access date, type, and the parts of the project they support. A cited author, publisher, or institution does not endorse this site.

Source type What it can support What it does not settle
Official / standards Time-zone identifiers, historical offsets, timestamp representation, calendar conversions, solar-term definitions. A particular Four Pillars interpretation or the truth of a symbolic association.
Classical text Vocabulary, sequence, textual rules, and historical framing. One universally accepted translation, authorship claim, or modern school.
Academic / editorial Scholarly context, documented disagreement, and the site’s own plain-English explanation. A claim that one interpretation is universal or that the publisher endorses this project.
Editorial The site’s own plain-English explanation and declared convention. A claim that the explanation is neutral, complete, or scientifically verified.

What this source page does not mean

  • Listing a source is not an endorsement by its publisher.
  • A calendar standard does not validate a metaphysical interpretation.
  • A classical text does not eliminate translation or school differences.
  • An access date records when this project consulted a page, not its scholarly completeness.
  • The inventory does not claim to include every relevant source.

Current calculation versions and convention choices are documented in the methodology page. For terminology, see the glossary.

Source does not mean endorsement.

The presence of a link here records what the project used and how far that use extends. It is not a claim of partnership, certification, or approval.
