# Create a Cron Using Cron Expressions

> **Note:** This SDK is currently in deprecation. Migrate to [JavaScript SDK](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/job-scheduling/cron/create-cron-expressions/) now.

Use this SDK to implement crons to schedule the submission of jobs to job pools. However, the configuration of the cron will be defined using regex-like expressions called [Cron Expressions](https://docs.catalyst.zoho.com/en/job-scheduling/help/cron/key-concepts/#cron-expressions).

> **Note:** In the following SDK, the cron has been configured using Cron Expressions, to submit a job to the job pool on **0Hrs 0Mins 0Secs** on **every 1st day of the week** on the **1st month of every year**. You can change this value as per your requirement by passing the relevant value to the `cron_expression` JSON key-value pair.

```javascript
// create function job meta
const jobMeta = {
job_name: 'test_job', // set a name for the job
target_type: 'Function', // set the target type as Function for function jobs
target_name: 'target_function', // set the target function's name (optional) (either target_id or target_name is mandatory)
// target_id: '123467890', // set the target functions's Id (optional) (either target_id or target_name is mandatory)
jobpool_name: 'test', // set the name of the function jobpool (optional) (either jobpool_name or jobpool_id is mandatory)
// jobpool_id: '1234567890' // set the Id of the function jobpool (optional) (either jobpool_name or jobpool_id is mandatory)
job_config: {
number_of_retries: 2, // set the number of retries
retry_interval: 15 * 60 // set the retry  interval
}, // set job config - job retries => 2 retries in 15 mins (optional)
params: {
arg1: 'test',
arg2: 'job'
}, // set params to be passed to target function (optional)
};
// create expression cron details
const expressionCron = {
cron_name: 'expression_cron', // set a name for the cron (unique)
description: 'expression_cron', // set a description for the cron (optional)
cron_status: true, // set the cron status as enabled
cron_type: 'CronExpression', // set the cron type as Calendar for daily, monthly and yearly
cron_expression: '0 0 * 1 1', // set the cron expression
// timezone: 'America/Los_Angeles', // set the timezone (optional)
cron_detail: {}, // set the cron details
job_meta: jobMeta // set function job meta
};
// create expression cron 
const expressionCronDetails = await jobScheduling.CRON.createCron(expressionCron);
```

> **Note:** We urge you to use this SDK to configure only [Dynamic Crons](https://docs.catalyst.zoho.com/en/job-scheduling/help/implementation/submit-job-dynamic-cron/). Use the *UI Builder* to configure [Pre-defined Crons](https://docs.catalyst.zoho.com/en/job-scheduling/help/implementation/submit-job-predefined-cron/).
