About This Schedule
The cron expression 0 */12 * * * runs a job twice a day — at 12:00 AM (midnight) and 12:00 PM (noon).
Twice-daily schedules are common for digest emails, daily data syncs, certificate renewal checks, and backup verification. The symmetry of midnight and noon makes it easy to predict and communicate.
If you need different times, specify them explicitly: 0 8,20 * * * runs at 8:00 AM and 8:00 PM instead.
