About this tool
Paste a cron schedule (5 fields or @daily-style macros) and see what each field means and the next run times in your time zone.
Fields are minute, hour, day of month, month and weekday with lists (,), ranges (-), steps (/) and names (JAN, MON). As in standard cron, when both day of month and weekday are set, a day matches if either matches.
Example: */15 9-17 * * 1-5 → every 15 minutes from 9:00 to 17:45, Monday to Friday.
Run times use the time zone of this device; servers often run cron in UTC. Quartz-style 6–7 field expressions (with seconds or ?) are not supported.
