Hi there,
We can add the date above the entry title like this:
add_action( 'generate_before_entry_title', function() {
$time_string = '<time class="entry-date published" datetime="%1$s" itemprop="datePublished">%2$s</time>';
$time_string = sprintf( $time_string,
esc_attr( get_the_date( 'c' ) ),
esc_html( get_the_date( 'l, F j, Y' ) )
);
?>
<div class="entry-meta custom-post-type">
<?php echo $time_string; ?>
</div>
<?php
} );
Adding PHP: https://docs.generatepress.com/article/adding-php/
Then you can disable the standard date in Customize > Layout > Blog.
Let me know if you need more info π
