Today is Saturday

Explanation:

In the above program, we imported the "Chrono" library to our project for performing date and time operations. We imported the Chrono library using the below line:

use chrono::prelude::*;

In the main() function, we got the current date and time using Utc::now() method. Then we compared today's weekday with other weekdays and printed the appropriate message.
