Frequently asked questions
- How is this different from the Cron Expression Explainer?
- This tool builds a cron expression from a schedule you describe (daily at 9am, every 15 minutes, etc). The Cron Expression Explainer goes the other direction — paste an existing expression and get a plain-English description of it.
- Does the generated expression get validated?
- Yes — every generated expression is parsed and explained by the same engine behind the Cron Expression Explainer, so what you copy is guaranteed to be a valid, well-formed 5-field cron expression, not just a string template.
- Does it support 6-field cron with seconds?
- No — standard 5-field cron only (minute, hour, day-of-month, month, day-of-week), which is what crontab and most schedulers use.
- Is my schedule uploaded anywhere?
- No. The expression is built entirely in your browser tab — nothing is sent to a server.
