What is a cron expression?

A cron expression is a string of 5 fields (minute, hour, day of month, month, day of week) that defines a recurring schedule. It is used by Unix/Linux systems, CI/CD pipelines, cloud schedulers, and task automation tools.

What does each field represent?

The 5 fields are: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7, where 0 and 7 = Sunday). Use * for 'any', */N for 'every N', and comma-separated values for lists.

What does */5 * * * * mean?

It means 'every 5 minutes'. The */5 in the minute field means 'at every 5th minute' — so at :00, :05, :10, :15, and so on, every hour, every day.

How do I schedule a job for every Monday at 9 AM?

Use '0 9 * * 1'. This means: minute 0, hour 9, any day of month, any month, day of week 1 (Monday).

Does this tool support seconds or 6-field cron?

This tool supports the standard 5-field cron syntax used by most systems (crontab, GitHub Actions, AWS CloudWatch). Some systems like Quartz use a 6th field for seconds — this is not supported.

Is my data sent to a server?

No. All parsing is performed entirely in your browser using JavaScript. No data is ever uploaded or transmitted.
