Frequently asked questions
What are the five cron fields?+
In order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), and day-of-week (0-6, where 0 is Sunday). Use *, ranges (1-5), lists (1,3,5), and steps (*/15).
How are the next run times calculated?+
The tool parses your expression into the allowed values for each field, then scans forward minute by minute from now to find the next matching times — in your local timezone.
How do day-of-month and day-of-week interact?+
Following standard cron: if both are restricted, a run fires when either matches. If only one is set, only that one applies.
