How to use

Enter a classic 5-field cron: minute, hour, day-of-month, month, day-of-week. Example: `0 9 * * 1-5` runs weekdays at 09:00.

Fields support `*`, ranges (`1-5`), lists (`1,15`), steps (`*/15`), and names for months or weekdays (MON, JAN).

The human summary explains the schedule in plain language. Next-fire times are shown in UTC—translate to your zone and remember DST shifts.
