    Current Day as Link

    Returns the URL to the current day’s archive as a link by displaying it within an anchor tag with the PHP echo command.

    
    <a href="<?php echo esc_url( get_day_link( false, false, false ) ); ?>"><?php _e( 'Today’s posts', 'textdomain' ); ?></a>
    
  2. Use With Variables

    PHP code block for use within The Loop: Assigns year, month and day of a post to the variables $arc_year, $arc_month and $arc_day. These are used with the get_day_link() tag, which returns the URL as a link to the daily archive for that post, displaying it within an anchor tag with the PHP echo command. See Formatting Date and Time for info on format strings used in get_the_time() tag.

    
    <?php 
    $archive_year  = get_the_time( 'Y' ); 
    $archive_month = get_the_time( 'm' ); 
    $archive_day   = get_the_time( 'd' ); 
    ?>
    <a href="<?php echo esc_url( get_day_link( $archive_year, $archive_month, $archive_day ) ); ?>">
    	<?php _e( 'This day’s posts', 'textdomain' ); ?>
    </a>
