Frequently asked questions
- What is a standard 5-part cron expression format?
- A standard Unix cron expression consists of five fields separated by spaces: Minute (0-59), Hour (0-23), Day of the Month (1-31), Month of the Year (1-12 or JAN-DEC), and Day of the Week (0-6 where 0 is Sunday, or SUN-SAT).
- What does the asterisk (*) mean in cron syntax?
- An asterisk (*) is a wildcard symbol representing every possible value for that field. For instance, an asterisk in the minute field triggers the job every single minute.
- How do step values (/) and commas (,) work in cron?
- A forward slash specifies step intervals (e.g., */15 in minutes means every 15 minutes). A comma allows listing multiple distinct values (e.g., 1,15 in day of month runs on the 1st and 15th).
- Can I use this generated cron expression in GitHub Actions or AWS EventBridge?
- Yes! Standard 5-field cron syntax is supported by crontab, GitHub Actions workflows, Kubernetes CronJobs, and modern cloud schedulers.
- Does this tool send my cron schedules to an external server?
- No. All cron parsing, explanation translation, and timestamp calculations run completely locally in your browser.
