The embedded holiday calendar tables (enabled by the default `calendars`
feature) are dated snapshots derived from primary sources: the published
calendars of NYSE / the Federal Reserve, the Bank of England, SIX Swiss
Exchange, the Japan Exchange Group, the Hong Kong Exchanges and Clearing, and
the Singapore Exchange; together with the ECB-defined fixed rule for TARGET2.
Each table is factual reference data; the snapshot date is recorded in that
file and in SPEC.md.
