About this tool
What this tool does
See every run of a cron or interval schedule in your timezone, including daylight-saving changes, without creating a job.
Limits and safe use
Five-field cron or a fixed interval, a horizon of up to 366 days and up to 2,000 listed runs. Time zone rules come from your browser. Review the report before relying on it. It is a deterministic check, not a certification, and it does not send data to a server or a model.
