Date with superscript or subscript number suffixes
Displays the date with a superscript or subscript st, nd, rd or th after the day. Because characters from the alphabet are used to represent the date format types, each of the HTML tag characters need to be escaped using a back slash. Superscript HTML tag is <sup> and subscript is <sub>.

<p><?php printf( __( 'Modified: %s', 'textdomain' ), get_the_modified_date('j\<\s\u\p\>S\<\/\s\u\p\> M Y') ); ?></p>
