The **date‑names** package provides ready‑to‑use, localized strings for month and weekday names (full and abbreviated), as well as AM/PM labels, for both Node.js and browser environments. It ships with a set of common locales (e.g., English, German, French, Spanish, Russian, etc.) and lets developers require a specific locale to obtain the appropriate translations, making it useful for any JavaScript project that needs simple, locale‑aware date label data.
