# Cloudflare Cron Triggers

Use Cron Triggers to start periodic Worker jobs. Fetch the relevant current documentation before implementing; configuration, API signatures, examples, and limits belong in the docs.

- **Set up a recurring job:** [Cron Triggers](https://developers.cloudflare.com/workers/configuration/cron-triggers/index.md) covers scheduling, deployment, and execution history.
- **Implement the job:** [Scheduled handler](https://developers.cloudflare.com/workers/runtime-apis/handlers/scheduled/index.md) covers controller properties, asynchronous work, and multiple schedules.
- **Schedule durable work:** [Trigger Workflows](https://developers.cloudflare.com/workflows/build/trigger-workflows/index.md) covers direct Workflow schedules and starting instances from a Worker. Check this before introducing a Worker whose only job is to start a Workflow.
- **Check capacity:** fetch [Workers limits](https://developers.cloudflare.com/workers/platform/limits/index.md) for the target plan and invocation type.
