What is a cron expression?

A cron expression is a five-field string that defines a schedule for recurring jobs. The fields are minute, hour, day of month, month, and day of week. Each field uses numbers, wildcards, ranges, or steps to define when the job runs.

How do I schedule a cron job for every 5 minutes?

Use */5 * * * * — the */5 in the minute field means 'every 5 minutes.' The wildcards in the other fields mean 'every hour, every day, every month, every day of week.'

What does * mean in a cron expression?

The asterisk (*) is a wildcard that matches every possible value for that field. In the hour field, * means 'every hour.' In the day-of-month field, * means 'every day.'
