What is a Cron Expression?

A cron expression is a text-based schedule used by cron implementations to define when recurring tasks should run. It is commonly used to schedule scripts, commands, maintenance jobs, backups and other automated tasks on Unix and Linux systems.

Cron Expression Format

A standard five-field cron expression contains minute, hour, day of month, month and day of week fields. Each field controls a different part of the schedule.

Minute: values from 0 to 59.

Hour: values from 0 to 23.

Day of Month: values from 1 to 31.

Month: values from 1 to 12.

Day of Week: values from 0 to 6, depending on the cron implementation.
