What cron format does this use?

It uses the standard 5-field crontab format: minute, hour, day-of-month, month, and day-of-week. Step (*/5), range (1-5), and list (1,3,5) values are all supported.

Does it run my cron job?

No. This is a generator and explainer — it describes the schedule a cron expression represents. You copy the expression into your own crontab or scheduler.
