Frequently asked questions
Which cron format is used?
The explainer reads minute, hour, day of month, month, and day of week fields.
Are lists and steps supported?
The explanation recognizes wildcard, comma-separated list, range, and step syntax.
Does it include seconds?
No. This tool expects the common five-field cron format without a seconds field.
Which timezone does cron use?
The expression has no timezone by itself. Actual timezone behavior depends on the scheduler where it runs.
Is the expression sent to a server?
No. Validation and explanation run locally in your browser.
