Begin with the source’s own compact description: “1823” is calendar year. The dossier treats that line as a proposition to test through calendar and year, not as a finished interpretation.
Why this record matters
The phrase “calendar year” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 1, 2026. The linked authority identifier is Q6988. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1823 and 1923.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
