Pricing

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 make a decision because of one.

Calendar API

Priced by how much of the world you need — not how often you ask. A payroll system in one country and a logistics platform spanning forty have different problems. Pricing follows geography, not request volume.

Calls are unlimited on every tier, including the free one. Dates computed from rules should be cached; metering requests would punish exactly the behaviour we recommend.

Dossiers

You are not paying for a country. You are paying for its complexity. Tuvalu and India are both countries. One runs on a handful of rules; the other spans states, exchanges and several calendars at once.

A standing order deliberately costs less than a single edition. Calendars expire. Governments revise dates, exchanges announce closures and ministries move deadlines — so a single edition is this year's almanac, not a perpetual licence. The value is in staying current.

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.

Questions people ask before buying

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.
