Run a Cron Job Every Sunday

Setting day-of-week to 0 (Sunday) with hour and minute at 0 creates a weekly schedule. Weekly crons are standard for maintenance windows, summary reports, and cleanup routines that do not need to run daily. Sunday midnight is the most common choice because it falls during the lowest-traffic period for most services.

The minute and hour are both 0 (midnight), and the day-of-week is set to 0, which represents Sunday in standard cron. Day-of-month and month are wildcards. The job fires once per week, specifically at the transition from Saturday night to Sunday morning. Some cron implementations also accept 7 for Sunday.
