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 recurring tasks. It is commonly used in Unix/Linux systems, CI/CD pipelines, and cloud services.
How do I read a cron expression?
Read left to right: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6, Sunday=0). An asterisk (*) means every value, and a slash (/) means intervals.
What does */5 mean in cron?
The */5 syntax means every 5 units. For example, */5 in the minute field means every 5 minutes (0, 5, 10, 15, ..., 55).
Is my data safe?
Yes. All processing happens in your browser. No data is sent to any server.
What cron formats are supported?
This tool supports standard 5-field cron expressions used by crontab, Kubernetes CronJobs, GitHub Actions, and most cloud schedulers.
