How to use
Set a Unix five-field expression, starting instant, time zone, and result count. Check candidate times even for expressions generated by the GUI.
Inspect weekdays, month boundaries, and daylight-saving changes. The tool neither interprets Quartz automatically nor registers jobs; verify the schedule on your actual scheduler too.
