JavaScript Date setMonth() method

setMonth() method is a Date class method, it is used to set the month to the Date object with a valid month value (between 0 to 11. 0 for January, 1 for February and so on).

Note: Month value larger than the 11 will be truncated from the starting month value (0), for example, we are going to set 12 as month value, it will be truncated at 0 and January will be set.

Syntax:

    var dt = new Date();
    dt.setMonth(month);

Examples:

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

    Function call to set the month:
    dt.setMonth(2);

    Function call to get the month:
    dt.getMonth(); 
    
    Output:
    2
