Guide & explanation
Build a Quartz-style cron expression, the form used by schedulers such as Quartz Scheduler and Spring @Scheduled.
Field layout

| Field | Range | Special characters |
|---|---|---|
| Seconds / Minutes | 0-59 | * , - / |
| Hours | 0-23 | * , - / |
| Day of month | 1-31 | * ? L W |
| Month | 1-12 / JAN-DEC | * , - / |
| Day of week | 1-7 (1=Sunday) | * ? L # |
The ? rule
Quartz requires either the Day-of-month or the Day-of-week field to be ? (meaning "no specific value"), because the two cannot both be pinned at once.
The tool shows the assembled expression, a plain-English summary, the meaning of each field, and range checks.
