How to read a cron expression
A standard cron expression has five fields separated by spaces: minute hour day-of-month month day-of-week. Each field accepts a number, a range (1-5), a list (1,15,30), a step (*/15), or * for "every value". The expressions above cover the schedules developers reach for most often.
