Frequently Asked Questions
What is a cron expression?▼
A cron expression is a string of five fields (minute, hour, day of month, month, day of week) that defines a schedule. For example, '0 9 * * 1-5' means 'at 9:00 AM, Monday through Friday'.
What does * mean in cron?▼
The asterisk (*) means 'every' — it matches all possible values for that field. So * in the hour field means 'every hour'.
