How to use it
Type or edit the five fields, or start from a preset. The sentence above the box explains the schedule, and the legend shows which field your cursor is in.
Questions
What do the five fields mean?
In order: minute, hour, day of the month, month and day of the week.
Does Magento read cron expressions the same way as Linux cron?
Almost. When both the day of the month and the day of the week are restricted, standard cron runs the job when either matches, while Magento runs it only when both match.
Why is my Magento cron job not running?
Check that the system crontab runs bin/magento cron:run every minute, that the job appears in the cron_schedule table, and that its group is not blocked by a long-running job.
