Run a Cron Job Daily at Midnight

Setting minute and hour to 0 with wildcards elsewhere creates the classic daily midnight job. This is the most common cron schedule for nightly batch processing, backups, log rotation, and report generation. Nearly every production system has at least one daily midnight cron for housekeeping and maintenance tasks.

Both the minute and hour fields are set to 0, pinning execution to exactly 00:00 (midnight). The day-of-month, month, and day-of-week fields are all wildcards, so the job fires once every day without any date restriction. This is the standard "once per day" cron pattern.
