JavaScript Date setHours() method

setHours() method is a Date class method, it is used to set the hour to the Date object with a valid hour value (between 00 to 23).

Note: Hour value larger than the 23 will be truncated from the starting hour value (0), for example, we are going to set 26 as an hour value, it will be truncated as 2.

Syntax:

    var dt = new Date();
    dt.setHours(hour);

Examples:

    Input/Date class object declaration:
    var dt = new Date();

    Function call to set the hour:
    dt.setHours(16);

    Function call to get the hour:
    dt.getHours(); 
    
    Output:
    16
