Problems validating schema for date time field

Hello, I’m sorry to hear that you’re experiencing issues with validating the date/time field for your schema. It seems like you’ve tried using the %date(Y-m-d)% and YYYY-MM-DD formats, but they are still not validating properly.

To ensure that the date is in ISO 8601 format, you can try using the following code snippet to add the time and timezone information to the datePosted field:

add_filter( 'rank_math/snippet/rich_snippet_jobposting_entity', function( $entity ) {
    if ( empty( $entity['datePosted'] ) ) {
        return $entity;
    }

    $entity['datePosted'] = wp_date( 'c', strtotime( $entity['datePosted'] ) );

    return $entity;
} );

This filter will add the time and timezone information to the datePosted field, ensuring that it is in ISO 8601 format. Once you’ve added this code to your theme’s functions.php or rank-math.php file, please retest the schema validation.

If you encounter any further issues or need additional assistance, please feel free to let us know. We’re here to help!

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

Can you please confirm if you’re checking the schema in the Rank Math Code Validation tab? If so, please note that Rank Math sometimes needs time to parse everything in the code validation tab, making it occasionally unreliable for testing but the Schema is applied correctly in the front end when you save the post. That’s why we always suggest checking the URL directly with Rich Results Test because that is what Google actually sees.

Let us know how it goes. Looking forward to helping you.
