Explain a cron expression and list the next runs, or build one with visual pickers
Enter or build a cron expression to see the result
Accepts 5 fields (min hour day month weekday) and 6 fields (with seconds), evaluated in your local time zone
Standard crontab has five fields — minute hour day-of-month month day-of-week; Quartz-style schedulers prepend a seconds field. Check which form your target system expects.
In standard crontab they are OR-ed: the job runs when either matches — a common configuration gotcha.
