Data for systems, dossiers for decisions.

The same source-labelled calendar underneath. What differs is who reads it — an application that computes with dates, or a person who has to act on one.

Calendar API

Priced by how much of the world you need — not how often you ask. Calls are unlimited on every tier, including the free one. Metering requests would penalise caching, which is exactly what we tell you to do with dates computed from rules.

Prices in

Country dossiers

Priced by depth, because depth is what varies. Every country is covered, but 129 of them hold ten observances or fewer while India holds 192. One price across that range would overcharge Tuvalu and badly undercharge India. Each cover prints its own count, so the band is checkable before you buy.

A standing order costs less than a single edition. That is deliberate. A calendar decays — a 2026 edition is near-worthless in 2027 — so a single edition is this year's almanac, not a perpetual licence. Pricing it below the annual would just invite people to re-buy it yearly instead of subscribing.

Every dossier is an annual entitlement: four editions a year, and the edition in force when you bought stays available for as long as you hold it.

What every plan includes

The assurance label

Every field says whether it was verified against an authority, corroborated across sources, or computed from a rule. Not an add-on — it is the product.

Immutable editions

The edition in force when you bought stays available for the life of your entitlement. A later edition never silently replaces the one you cited.

Named provenance

Every observance can name the gazette, ministry or exchange notice behind it, and the date we last checked it.

No lock-in

Bulk export as CSV and ICS on paid tiers. If you leave, you leave with the data you paid for.

Not sure which? Start on the free developer tier — no card, no expiry — and check coverage for your jurisdictions first. If something you need is missing, ask before you buy.
