About this tool

Decode any 5- or 6-field cron schedule into a human-readable description, preview the next few fire times, and catch malformed expressions — useful for crontabs, GitHub Actions and job schedulers.

It runs completely in your browser — no input is sent anywhere, and this page loads no ads or third-party scripts, so it is safe to use with data you would not paste into a hosted service.
