What is a Cron expression?

A Cron expression is a string comprising five or six fields separated by white space that represents a set of times, normally as a schedule to execute some routine.

What do the 5 parts of the cron string mean?

They represent: Minute (0-59), Hour (0-23), Day of the month (1-31), Month (1-12), and Day of the week (0-7, where 0 and 7 are Sunday).
