Cron: every hour

The cron expression `0 * * * *` fires at the top of every hour. The shorthand `@hourly` means the same thing in most runners.

# expression

0 * * * *

Means: At minute 0 of every hour — :00 every hour, 24 times a day.

→ Open in cron builder (pre-filled)

# common use cases

Hourly aggregations rolled into a time-series store.
Rate-limited integrations where one call per hour is the budget.
Refreshing tokens, dashboards, or caches with hourly TTLs.

# next fires (sample)

01:00
02:00
03:00
04:00
05:00

# pitfalls

`@hourly` is the same expression in Unix cron, Kubernetes, and most Node libs. GitHub Actions and Cloudflare Workers reject the macro — use `0 * * * *` to stay portable.
Hourly fires in a DST-observing timezone may double or skip during transitions. Schedule in UTC for safety.
