WordPress Custom Query to show posts from last x years

I have found a way to show all posts from the current year with this code:

<?php
$today = getdate();
$lastyear = $today[ 'year' ];
$args = array( 
    //'nopaging' => true,
    'paged' => $paged,
    'category' => 1, 
    'posts_per_page' => 36,
    'year' => $lastyear,
);
query_posts( $args ); // The Query ?>

    <div id="grid">

    <?php while ( have_posts() ) : the_post(); // The Loop ?>
        <?php get_template_part( 'article', 'thumb' ); ?>
    <?php endwhile; ?>

    </div>

    <?php get_template_part( 'navigation' ); ?>

<?php wp_reset_query(); // Reset Query ?>

However, what I really want is to show posts from 2 years ago till today (it’s Jan 2014), meaning, posts from 2012 and 2013 and 2014. How do I do this?

Many thanks in advance.
