Variations
Common use cases
- Sending daily standup or status digest emails.
- Generating start-of-day operational reports.
- Posting daily metrics summaries to chat channels.
- Triggering a morning ETL job that prepares data for the workday.
Gotchas
- Most schedulers default to UTC — 09:00 UTC is 1 AM Pacific, 4 AM Eastern. To run at 9 AM local, set `spec.timeZone` (K8s), `CRON_TZ` (crontab), or `zone` (Spring `@Scheduled`).
- AWS EventBridge and GitHub Actions are always UTC — to run at 9 AM Pacific, schedule for 17:00 UTC during standard time and 16:00 UTC during daylight time (you'll need two rules with date ranges, or accept a 1-hour drift).
- On daylight saving spring-forward day, a 9 AM local job runs normally — the transition happens at 2 AM.
0 9 * * * is one of the most-written cron expressions in the wild. It’s the schedule for “I want this to greet me in the morning.” The actual greeting time depends on the timezone — make sure the scheduler agrees with you about what “9 AM” means.
Frequently asked questions
What does `0 9 * * *` mean?
Minute `0` and hour `9` mean "at 09:00." The three asterisks for day-of-month, month, and day-of-week mean "every day." One invocation per day.
How do I make `0 9 * * *` fire at 9 AM local time instead of UTC?
Depends on the scheduler. Linux crontab uses system timezone by default. For Kubernetes, set `spec.timeZone: "America/Los_Angeles"` (requires K8s 1.27+). For Spring, use the `zone` parameter on `@Scheduled`. AWS EventBridge and GitHub Actions are always UTC — you'll need to offset the hour manually.
Is `0 9 * * *` the same as `0 9 * * 0-6`?
Yes — `*` in the day-of-week field is equivalent to `0-6` (every day). Both fire every day of the week. The asterisk form is more idiomatic; the explicit range is sometimes used for clarity.
What happens on daylight saving days?
If the scheduler is timezone-aware (Kubernetes 1.27+ with `spec.timeZone`, Spring with `zone`, crontab with `CRON_TZ`), the job correctly fires at 9 AM local time — even though the underlying UTC offset shifts. If the scheduler is UTC-only (EventBridge, GitHub Actions), the wall-clock firing time shifts by an hour twice a year.
