Create custom cron jobs in Magento

Magento's cron system lets you schedule tasks to run automatically at specific times. Let's build a custom cron job from scratch.

Create a custom cron job

First, create a crontab.xml file in your module's etc directory:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
    <group id="default">
        <job name="vendor_module_your_task" instance="Vendor\Module\Cron\Foo" method="execute">
            <schedule>0 2 * * *</schedule>...
