Frequently Asked Questions

The cron expression for every 2 hours is 0 */2 * * *. The 0 means minute 0, and */2 in the hour field means every 2nd hour. This runs at 12:00 AM, 2:00 AM, 4:00 AM, etc.
Use 0 1,3,5,7,9,11,13,15,17,19,21,23 * * * to run at odd hours. Or use 0 1/2 * * * (1/2 means 'starting at 1, then every 2 hours') if your cron implementation supports it.
In the hour field, */2 means 'every 2nd hour starting from 0'. So it runs at hours 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and 22 - a total of 12 times per day.
