Reading a cron expression

From left to right, the fields select minute, hour, day of month, month, and day of week. For example, */15 9-17 * * 1-5 means every fifteen minutes during working hours from Monday through Friday. Confirm critical schedules in the exact cron implementation that will execute them.
