Cron: Every Sunday (0 0 * * 0)

The cron expression 0 0 * * 0 translates to “At 00:00, on Sunday”. It is one of the most commonly used schedules (every sunday).

The day-of-week field is `0`, which cron reads as Sunday, so with minute 0 and hour 0 the job runs once a week at 00:00 on Sunday. (Cron also accepts `7` for Sunday, so `0 0 * * 7` is equivalent.) Sunday-at-midnight is a favourite for end-of-week wrap-up work that should finish before Monday: weekly backups, log archival, rebuilding an index, or a "week in review" email. Since Sunday midnight sits at the boundary between weeks, decide clearly whether the run belongs to the week just ending or the one about to start when you compute date ranges inside the job.
