Frequently Asked Questions
What is a cron expression and how is it used?
A cron expression is a five-field string (minute, hour, day of month, month, day of week) that defines a recurring schedule for automated tasks. It is the standard scheduling format used by Linux crontab, Kubernetes CronJobs, GitHub Actions workflows, and AWS CloudWatch rules.
How do I read a crontab schedule expression?
Read the five fields left to right: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6 where Sunday is 0). An asterisk (*) matches every value, a slash (/) sets intervals, and a comma separates individual values. For example, 0 9 * * 1-5 means 9:00 AM every weekday.
What does */5 mean in a cron expression?
The */5 syntax means every 5 units of that field. Placing */5 in the minute field runs the job at minutes 0, 5, 10, 15, and so on through 55. This step syntax works in any cron field and is widely used for polling intervals and periodic health checks.
Is my data safe?
Yes. All cron expression building and validation happens entirely in your browser. No schedule data is sent to any server, collected, or stored.
Which cron formats and platforms are supported?
This generator supports the standard 5-field cron syntax compatible with Unix crontab, Kubernetes CronJobs, GitHub Actions, GitLab CI, AWS EventBridge, and most cloud task schedulers. It also previews the next scheduled run times so you can verify your expression before deploying.
