Frequently asked questions
What is a cron expression?
A cron expression is a compact schedule. The standard 5-field form is minute, hour, day of month, month, and day of week.
When should I use the 6-field format?
Use 6 fields when the scheduler supports seconds. The extra field comes first: second minute hour day-of-month month day-of-week.
What happens if day of month and day of week are both set?
In standard cron the job runs when either field matches (OR, not AND). Leave one as every (*) unless you want that behavior.
Is my data private when using Cron Expression Generator?
Yes. The generator runs entirely in your browser. Your inputs are never uploaded to Utilvia servers.
