Cron: Every 6 hours (0 */6 * * *)

The cron expression 0 */6 * * * translates to “At minute 0, every 6 hours”. It is one of the most commonly used schedules (every 6 hours).

The `*/6` hour step with minute 0 fires four times a day - at 00:00, 06:00, 12:00 and 18:00 - splitting the day into clean six-hour quarters. This cadence suits work that should happen a few times daily but not every hour: nightly-ish reports you want more than once, data refreshes across time zones, or maintenance windows. Four runs a day keeps costs and noise low while still catching changes within a quarter of a day. Remember cron uses the server clock (UTC on most hosts), so those quarters may not line up with your local morning and evening.
