# Update Cron

> **Note:** Ensure you have installed the [required package](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/job-scheduling/overview/#prerequisites) to use this SDK method.

You can use the `updateCron()` SDK method to update the name, description, and target of a [Pre-defined](https://docs.catalyst.zoho.com/en/job-scheduling/help/implementation/submit-job-predefined-cron/) or [Dynamic](https://docs.catalyst.zoho.com/en/job-scheduling/help/implementation/submit-job-dynamic-cron/#configure-a-dynamic-cron) cron. 

You can select your required cron by passing the [cron ID](https://docs.catalyst.zoho.com/en/job-scheduling/help/cron/key-concepts/#cron-id) to the [`getCron()`](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/job-scheduling/cron/get-cron-details/) method, and update the details using the `updateCron()` method.

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.

```javascript
const cron = await jobScheduling.CRON.getCron('test_cron'); // get cron
cron.cron_name = 'test';
const updatedCronDetailsWithName = await jobScheduling.CRON.updateCron('test_cron', cron); // update cron details with cron name
updatedCronDetailsWithName.cron_name = 'test_new';
const updatedCronDetailsWithId = await jobScheduling.CRON.updateCron('1234567890', updatedCronDetailsWithName); // update cron details with cron id
```
