What does * * * * * mean?

A cron string with five asterisks means 'every minute of every hour of every day of the month, every month, and every day of the week'. It triggers every 60 seconds.

What is the difference between / and - in cron?

A hyphen (-) specifies an inclusive range, such as 9-17 (every hour from 9 AM to 5 PM). A forward slash (/) specifies a step interval, such as */15 (every 15 minutes).

Does this tool work with Linux crontab, GitHub Actions, and AWS CloudWatch?

Yes. The standard 5-field format generated by ZORIQ is universally supported by Linux crontab, GitHub Actions schedules, Kubernetes CronJobs, and AWS EventBridge.
