Frequently Asked Questions

What is a cron expression?

A cron expression is a string of 5 fields (minute, hour, day, month, weekday) that defines a schedule for recurring tasks. Example: '0 9 * * 1' means every Monday at 9:00 AM.

What does * mean in cron?

The asterisk (*) means 'every' — it matches all possible values for that field. For example, * in the hour field means every hour.

What is the difference between 5-field and 6-field cron?

Standard Unix cron uses 5 fields. Some systems add a 6th field for seconds. This generator uses the standard 5-field format.
