# Get the business-day calendar

> The honored national holiday calendar for a year plus the verified BCB-artifact provenance (source, retrieval instant, sha256, covered years), projected verbatim from the compiled artifact (D-4). year defaults to the current year; a year outside the artifact's coverage returns a clean 404.
