How do I add days to a Chrono UTC?

I am trying to find the preferred way to add days to a Chrono UTC. I want to add 137 days to the current time:

let dt = UTC::now();

Just use Duration and appropriate operator:
use chrono::{Duration, Utc};

fn main() {
let dt = Utc::now() + Duration::days(137);

println!("today date + 137 days {}", dt);
}


Test on playground.
