Frequently Asked Questions

What is a cron expression?

A cron expression is a string of five fields (minute, hour, day of month, month, day of week) that defines a schedule for running automated tasks. For example, '0 9 * * 1' means 'every Monday at 9:00 AM'. The tool helps you build these expressions visually.

What cron format does this tool use?

The tool uses the standard 5-field cron format (minute, hour, day of month, month, day of week) compatible with Unix crontab, GitHub Actions, AWS CloudWatch, and most job scheduling systems.

Can I see when my cron job will next run?

Yes. The tool shows the next 5 scheduled execution times for your cron expression, so you can verify that your schedule works exactly as intended before deploying it.

What does the asterisk (*) mean in cron?

The asterisk (*) means 'every' or 'any value' for that field. For example, * in the hour field means 'every hour', and * in the day-of-week field means 'every day'. You can also use */5 to mean 'every 5 units' (e.g., */15 in minutes = every 15 minutes).

Yes, completely free with no signup. Build cron expressions visually, see human-readable descriptions, and verify upcoming execution times. The tool runs entirely in your browser with no data sent to any server.
