About This Schedule
The cron expression 0 */4 * * * runs a job every 4 hours — at 12:00 AM, 4:00 AM, 8:00 AM, 12:00 PM, 4:00 PM, and 8:00 PM. That's 6 executions per day.
Every 4 hours is a practical schedule for tasks like database maintenance, periodic backups, API rate-limited data fetching, and shift-based reporting.
