GetPostsQuery search in two categories

Hi, I need to make a query to get posts from two or more categories.
Now I’m using this to get posts from one category:

// Define the query
$args1 = array();
$args1['post_type'] = 'post';
$args1['post_status'] = 'publish';
$args1['taxonomy'] = 'category';
$args1['taxonomy_slug'] = 'my-taxonomy-slug';
$args1['date_column'] = 'my-date';
$args1['date_min'] = date('Ymd');
$args1['orderby'] = 'my-date';
$args1['order'] = 'ASC';

How can I select posts form more taxonomy slugs?
