Frequently asked questions
What do the five fields mean?
In order: minute, hour, day of month, month and day of week. An asterisk means every value of that field.
What does */5 mean?
Every fifth value of that field starting from zero. In the minute field that is minute 0, 5, 10 and so on, so the job runs twelve times an hour.
Why did my job run more often than expected?
Usually because day of month and day of week are both set. Cron treats them as OR, not AND, so the job fires on either condition.
