You need to pass the required cron configurations as a JSON object to the createCron() SDK method to create your required recurring cron. The interval of a recurring cron can range anywhere from a minute to entire calendar years. With respect to its schedule type, there are four types of recurring cron: **Every**, **Daily**, **Monthly**, and **Yearly**. The `jobScheduling` reference used in the code snippets below is the [component instance](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/job-scheduling/create-instance/) created to perform these operations. **Every Cron** > **Notes:** * The following SDK is written for a job that will trigger a [Job Function](https://docs.catalyst.zoho.com/en/serverless/help/functions/job-functions/). To make the SDK compatible for the other types, you need to replace the value with proper [Job Pool ID](https://docs.catalyst.zoho.com/en/job-scheduling/help/jobpool/key-concepts/#job-pool-id), or **Job Pool Name**, and provide the appropriate **Target Name**, or **Target ID**. * The following SDK is configured to submit a job every **two hours**, **one minute**, and **three seconds**. You can change this value as per your requirement by passing the relevant value to the `cron_detail` JSON key-value pair. The following SDK can be used to create a recurring cron that will submit a job to the job pool at a scheduled interval that is **less than 24Hrs**. #### Parameters Used You need to construct two JSON objects, one that provides the meta of the job that needs to be submitted and the other is to contain your cron's meta that will schedule the submission of the job to the job pool. The JSON attributes used in these two JSONs are provided in the following table:
