Cron: Every hour (0 * * * *)

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

Here the minute field is pinned to 0 while the hour stays a wildcard, so the job fires exactly once an hour, always at the top of the hour (1:00, 2:00, 3:00 and so on). This is the classic "hourly job" and one of the most-used schedules in production: hourly rollups, log rotation, cache warming, sending digest notifications. Pinning the minute to 0 (rather than leaving it as `*`) is the crucial detail - forget it and you get the every-minute schedule instead.
