Two Different Excerpt Lengths

Hi, I’m hoping to have two different excerpt lengths determined by page. For example, on my home page I want the excerpts around 20 words, but on the Archives pages I want them closer to 60. I’ve read lots of posts on this topic, but none seemed to work for me. Though this idea is the closest to what I’m hoping for:

function custom_excerpt_length($length) {
    if (is_page('Events')) {  //For the events page
        return 65;
    } else {
        return 40; //for all others pages
    }
}
add_filter('excerpt_length', 'custom_excerpt_length');
