What is Cron expression explainer?

Cron Expression Explainer — Turn any cron expression into plain English with this free cron explainer — decode crontab schedules instantly. No signup; runs fully in your browser.

Parsing and description are done entirely by the vendored cronstrue engine (bradymholt/cronstrue, MIT) via its toString function, which parses the five or six cron fields and renders a human-readable sentence. The wrapper only validates the form value and forwards the engine's own parse error for invalid expressions. All computation happens in your browser; nothing is uploaded. Limitation: the description follows standard cron semantics — it cannot account for your scheduler's timezone or non-standard extensions.
