Cron Syntax

A standard cron expression contains five fields separated by spaces:

minute hour day-of-month month day-of-week

* matches every allowed value.
, separates multiple values, such as 1,15,30.
- defines a range, such as 1-5.
/ defines an interval, such as */10.

This tool targets the common five-field Linux and Unix cron format. Some services use additional fields or platform-specific syntax.
