Home is where your website starts but by default, Home doesn’t show up in your WordPress menu. Add this bit of code to your functions.php and it will magically appear:

function home_page_menu_args( $args )
{
  $args['show_home'] = true;
  return $args;
}
add_filter( 'wp_page_menu_args', 'home_page_menu_args' );

Format any date you like according to the date formatting settings in the WordPress backend with this simple piece of code. Put the following function in your theme’s functions.php file and enjoy the magic anywhere in your theme.

// $date is in yyyy-mm-dd format
function any_date($date = '2011-10-28')
{
  $format = get_option('date_format');
  return apply_filters('get_the_time', mysql2date($format, $date), $format);
}

Another useful piece of code for you to put into your functions.php file. You probably already know that a file in your theme dir called category-1.php will be used for showing content for the category that has an id of 1. The filters below allow you to have hierarchical templates based on category id. For instance, all single posts belonging to category 1 will use single-cat-1.php. Also, all child categories of category 1 will use category-1.php.
