What is a Cron expression?

A Cron expression is a string of 5 or 6 fields separated by spaces that defines a recurring schedule for tasks in Linux, Unix servers, and cloud automation platforms.

What do the 5 fields in a standard Cron expression represent?

In order: Minute (0-59), Hour (0-23), Day of Month (1-31), Month (1-12), and Day of Week (0-6 or 1-7, where Sunday is 0 or 7).
