What to know The same as 0 0,6,12,18 * * *. Six divides 24, so the runs are evenly spaced. To run at 03:00, 09:00, 15:00 and 21:00 instead, use 0 3-23/6 * * * or list the hours.
Variations
0 3-23/6 * * *every 6 hours, starting at 03:00 At 03:00, 09:00, 15:00 and 21:00.
0 */4 * * *every 4 hours At 00:00, 04:00, 08:00, 12:00, 16:00 and 20:00.
Gotchas 0 */5 * * * is not "every 5 hours": it runs at 00, 05, 10, 15 and 20, then 00 again after only 4 hours.← Explain any cron expression
