Post Date Provide short Date I want it to be ISO 8601 Format

Hello,

Thank you for contacting Rank Math support today.

Can you please confirm if you are referring to this date in the Job Posting schema?

We are looking forward to helping you.

Hello,

Thank you for keeping in touch with us.

In this case, this can be done by having a PRO version of Rank Math and you may need to create a custom variable to insert it into the “Date Posted” field in your JobPosting Schema. You can follow the filter provided in your last ticket and enable the advanced Schema builder provided by the PRO version.

If using a PRO version is not an option, then you can make use of this filter to modify your schema:

/**
 * Collect data to output in JSON-LD.
 *
 * @param array  $unsigned An array of data to output in json-ld.
 * @param JsonLD $unsigned JsonLD instance.
 */
add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
	return [];
}, 99, 2);

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
