FAQ
Does this support seconds or Quartz Cron?
This tool supports standard five-field POSIX Cron, without seconds, years or Quartz extensions such as ?, L, W and #.
What happens when both day-of-month and weekday are set?
It follows common POSIX semantics: when neither field is a wildcard, a match in either field triggers the schedule.
