Frequently asked questions
What do the five fields in a cron expression represent?
They represent minute, hour, day of month, month, and day of week, in that order, each defining when the scheduled job should run.
What does an asterisk mean in a cron expression?
An asterisk means 'every' for that field, so an asterisk in the hour field means the job runs every hour.
