setHours < Date < JavaScript

The setHours() method of the Date object changes the hours for the date according to local time. (The minutes, seconds and milliseconds can be passed/changed, too.)

    
    const event = new Date('July 20, 2020 21:36:00');

    event.setHours(10);

    const newHours = event.getHours();

    console.log(newHours);
    // 10
