Cron Wednesday at 3 AM

The cron expression 0 3 * * 3 fires at 3:00 AM every Wednesday. This mid-week, early-morning slot is a classic maintenance window — far enough from business hours to avoid impact, and mid-week to allow follow-up during business days.

Wednesday at 3 AM is used for mid-week database maintenance, patch application windows, scheduled restarts, data migration runs, and infrastructure updates. The 3 AM timing targets the lowest-traffic period for most applications.

If you need both a mid-week and weekend maintenance window, add a Sunday run: use two cron entries — 0 3 * * 3 and 0 3 * * 0 — or combine them: 0 3 * * 0,3.
