Workflows, Workers – Schedule Workflow instances directly from your Workflow binding

You can now attach cron schedules directly to a Workflow binding in wrangler.jsonc. Each scheduled run creates a new Workflow instance automatically, so you do not need to define a separate Worker with a scheduled handler just to trigger your Workflow on an interval.

For example, you can configure hourly, every-15-minute, or weekday schedules on the same Workflow:

{
  "workflows": [
    {
      "name": "my-scheduled-workflow",
      "binding": "MY_WORKFLOW",
      "class_name": "MyScheduledWorkflow",
      "schedules": ["0 * * * *", "*/15 * * * *", "0 9 * * MON-FRI"]
    }
  ]
}

This makes it easier to build recurring jobs such as database backups, invoice generation, report aggregation, and cleanup tasks without wiring up a separate Cron Trigger entrypoint.
