birthday

The tool provides a command‑line interface for storing and querying birthday information. Users can add entries by specifying a person’s name and birth date, retrieve upcoming birthdays by supplying a future date, and list all stored dates. The data are kept in a JSON file that can be overridden with a custom path, allowing multiple collections or integration with other scripts.

It is intended for individuals who want a simple, local way to track friends’ birthdays without relying on external services. The CLI can be installed globally via npm or yarn, and the same functionality is exposed as a JavaScript library for programmatic use in Node.js projects.

The package is released under the MIT license and includes documentation, help commands, and contribution guidelines. It is marked as stable and is available for free, with optional community support channels listed in the repository.
