Frequently Asked Questions

Does Google Cloud Scheduler support timezones? ▾
Yes — unlike AWS EventBridge and GitHub Actions, each Cloud Scheduler job has an optional "timeZone" field (e.g., "America/New_York"). The cron expression is evaluated in that timezone.
What HTTP methods does Cloud Scheduler support for targets? ▾
Cloud Scheduler supports GET, HEAD, POST, PUT, DELETE, PATCH, and OPTIONS. The target can be an HTTP/HTTPS endpoint, a Cloud Pub/Sub topic, or an App Engine HTTP endpoint.
Is Cloud Scheduler the same as Cloud Tasks? ▾
No — Cloud Scheduler is for recurring scheduled jobs (cron-based). Cloud Tasks is for one-time delayed task execution (like a job queue with delay). They serve different purposes and can be combined.
What happens if a Cloud Scheduler job fails? ▾
Cloud Scheduler retries failed jobs with exponential backoff up to 5 attempts by default. You can configure the retry count, minimum/maximum backoff, and max doublings in the job settings.
How fine-grained can Cloud Scheduler run? Is every-minute supported? ▾
Yes — Cloud Scheduler supports the full standard cron expression set, including every-minute ("* * * * *"). The minimum interval is 1 minute.
