Cron Every 10 Hours

The cron expression 0 */10 * * * triggers at the top of every 10th hour — at 00:00, 10:00, and 20:00 each day. Since 24 doesn't divide evenly by 10, the gap between the last run (20:00) and the first of the next day (00:00) is only 4 hours instead of 10.

This three-times-a-day schedule works for tasks that need periodic attention but not hourly: data warehouse refreshes, periodic compliance checks, and regular external API syncs. However, the uneven gap may cause issues if your job expects uniform spacing.

For truly even three-times-a-day execution, use 0 */8 * * * (every 8 hours at 00:00, 08:00, 16:00). For twice daily, 0 */12 * * * runs at midnight and noon.
