Frequently Asked Questions
A cron expression is a string of 5 fields (minute, hour, day-of-month, month, day-of-week) that defines a recurring schedule. For example, '0 9 * * 1-5' means 'at 9:00 AM every weekday'. It's used in Unix/Linux cron jobs, CI/CD systems, and cloud schedulers.
* means 'every', */n means 'every n units', a-b means 'range from a to b', a,b means 'at a and b'. For example, */15 in the minute field means 'every 15 minutes', 1-5 in day-of-week means 'Monday through Friday'.
