Build cron with dropdowns.

A visual cron expression builder — pick from dropdowns for every field and get a ready-to-paste cron string.

Don't memorize cron syntax. Pick from dropdowns for each field — the cron expression and plain-English translation update live as you click. Send the result to the explainer when you're done.

Build a cron expression

Cron expression * * * * *
In plain English Every minute
    How it works

    Build, preview, ship.

    1. Pick a mode for each field. "Every minute", "at specific minute", "every N minutes", etc. The detail panel below shows the right controls for that mode.
    2. Watch the preview update. Both the cron string at the top AND the plain-English translation update every time you click a dropdown or checkbox.
    3. Click a preset for a head start. Common patterns like "weekdays at 9 AM" or "every 15 minutes" pre-fill all the fields for you.
    4. Send to the explainer. When you're happy, click Open in Explainer → to load the expression into the main cron tool for next-run previews, syntax highlighting, and more.

    This tool produces standard Unix 5-field cron. For Quartz, AWS, GitHub Actions, or other platforms, build it here, then load it into a platform-specific tool for the right validation rules.
