What is running

Three things, three clocks.

The engine, the corpus and the dossiers each carry a version, and they move independently — so "updated" on its own is never a complete answer. This is what each one is, which version is current, and what makes it change.

Engine

v1.49.0version

The running API. Serves every query, and is the thing a key authenticates against.

25 September 2026released · 2 days ago

3,992 dated closures · 241 jurisdictions

Ships as a tagged container image, when a release is cut. Its exact build time is always available at /v1/health.

Corpus

2026.09edition

The data itself — the holidays, market closures and deadlines, with the evidence behind each.

1 September 2026published · 26 days ago

digest af2c1caf943c8dff

A new edition monthly, superseding 2026.08. Next expected 2026-10-01. How editions work.

Dossiers

The per-country PDFs. Cut from an edition, dated on the cover, and citable.

Rebuilt when the edition they were cut from is superseded. A copy you bought keeps working — it is a dated document, not a subscription to a moving one. Refunds.

Every figure here is read from the build rather than typed, so this page cannot claim a version that is not the one running. What changed, and when, is on the changelog; corrections to the data are in the errata log.
