FAQ
What is the cron format?
Five fields separated by spaces: minute hour day-of-month month day-of-week. * means every value, */5 every 5th, 1-5 a range and 1,15 a list.
Which timezone does cron use?
The server's timezone (often UTC). Kubernetes CronJobs, GitHub Actions and most cloud schedulers run in UTC unless configured otherwise — switch the preview to UTC to check.
Day-of-month and day-of-week together?
In classic cron, if both fields are restricted the job runs when either matches (OR), not both. This tool follows that rule.
