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 recurring schedule. Cron is used in Unix/Linux systems, CI/CD pipelines, cloud schedulers, and task automation tools.
What does * mean in cron?
The asterisk (*) is a wildcard that means every possible value for that field. For example, * in the minute field means every minute, and * in the hour field means every hour.
How do I run a job every 5 minutes?
Use */5 in the minute field: */5 * * * *. The /5 notation means every 5th minute.
What is the difference between 5-field and 6-field cron?
Standard cron uses 5 fields (minute through day-of-week). Some systems like Quartz and Spring add a sixth field for seconds at the beginning. This tool generates standard 5-field expressions.
