Frequently Asked Questions
What does "0 0 * * *" mean?
It is five fields: minute hour day-of-month month day-of-week. That example runs at minute 0, hour 0 (midnight), every day, every month, any weekday — i.e. daily at midnight UTC.
Why did my cron not fire?
Timezone mismatch is the usual cause — many schedulers run in UTC while you expected local time. The parser shows the next run times so you can verify.
Can I express every 5 minutes?
Yes: "*/5 * * * *" means every 5 minutes. The step syntax */n works on any field.
