How does a cron-expression generator work?

A cron generator translates a visual schedule into the five fields used by a standard Unix crontab: minute, hour, day of month, month, and day of week. It also describes the expression in plain language, helping catch schedules that would otherwise run more often or at a different time than intended.

The parser supports wildcards, steps, ranges, and lists in the standard five-field format. It does not emit seconds-level Quartz, Spring, or node-cron expressions. Because day-of-month and day-of-week rules may interact with OR behavior in cron implementations, the generated description should be reviewed before deploying a job.
