# Update Cron

The following SDK can be used to update a particular cron's details. You can use this SDK to update the name, description and target. 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 `get()` method, and update the details using the `update()` method.

> **Note:** You can use this method to update details of both [Pre-Defined Crons](https://docs.catalyst.zoho.com/en/job-scheduling/help/implementation/submit-job-predefined-cron/) and [Dynamic Crons](https://docs.catalyst.zoho.com/en/job-scheduling/help/implementation/submit-job-dynamic-cron/).

**Using Cron ID**

```python
cron = job_scheduling.CRON.get('test') # get cron with cron name
cron.__setitem__('cron_name', 'test_new_name') # set cron name
updated_cron = job_scheduling.CRON.update('1234567890', cron) # updating cron name with cron Id

```

**Using Cron Name**

```python
cron = job_scheduling.CRON.get('test') # get cron with cron name
cron.__setitem__('cron_name', 'test_name') # set cron name
updated_cron = job_scheduling.CRON.update('test', cron) # updating cron name with the existing cron name

```
