Cron: Every 2 hours (0 */2 * * *)

The cron expression 0 */2 * * * translates to “At minute 0, every 2 hours”. It is one of the most commonly used schedules (every 2 hours).

Minute 0 combined with the `*/2` step in the hour field means the job runs at midnight, 02:00, 04:00 and on through the day - twelve times in 24 hours, always on even-numbered hours. It is the go-to when hourly is more often than you need but daily is too coarse: think periodic backups, syncing with a partner system, or recomputing something moderately expensive. Because the hour step counts from 0, the runs land on 00, 02, 04… rather than odd hours - shift the start by writing `0 1-23/2 * * *` if you want the odd ones instead.
