tzdata-backward

Part of the IANA time zone database (backward compatibility zones) distributed as JSON for Node.js and browsers. Version 1.0.49 corresponds to tzdata 2026b. This module is part of a split package strategy, requiring peer dependencies for other region modules (tzdata-africa, tzdata-asia, etc.) because the data contains links to zones in those modules. Designed primarily for use with timezonecomplete library, but usable standalone for time zone data consumption. Releases follow IANA tzdata releases. The 'backward' module contains historical zone names that map to canonical zones.
