Cron is a time-based job scheduler in Unix-like operating systems. A cron expression describes a recurring schedule using five space-separated fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7, where both 0 and 7 mean Sunday).
Cron is commonly used to run scripts, backups, reports, and maintenance tasks at regular intervals without manual intervention.
Field syntax: *, /, -, and ,
Day-of-month and day-of-week work as a logical OR when both are non-wildcard. These constructs can be mixed: 1-5/2 means "every 2nd value from 1 to 5", i.e. 1, 3, and 5.
Common cron patterns
Most cloud schedulers (GitHub Actions, Cloud Run Jobs, AWS EventBridge) accept the same 5-field syntax. Some also support a 6-field format with seconds as the first field — this tool uses the standard 5-field format.
