CRON Syntax Summary

The CRON expression is composed of five parts, separated by spaces, representing minute, hour, day of month, month, and day of week respectively, as illustrated below.


                    The CRON expression is composed of five parts, separated by spaces,
                        representing minute, hour, day of month, month, and day of week
                        respectively.

The channel runs when the fields in the expression match the current time and date. An asterisk (*) acts as a wildcard and represents all values. If both “day of month” and “day of week” are specified (not *s), then the schedule will run for both.

Each part can specify either one value or a repeating value. A number by itself represents a single value while a number preceded by an asterisk and a forward slash represents a repeating value. For example, in the second position, “5” means “on the fifth hour (5:00 AM)” and “*/5” means “every fifth hour (5:00 AM, 10:00 AM, 3:00 PM, etc).” The table below provides some examples.
