JavaScript Date getMonth() Method
The date.getMonth() method is used to fetch the month(0 to 11) from the given Date object (0 represents the first month of the year).
Syntax:
DateObj.getMonth()Parameter:
- This function does not accept any parameter.
Return Value:
- It returns the Month for the given Date object. The month is an integer value ranging from 0 to 11. Zero (0) means January, 1 means February, and so on till 11 means December.
Example 1: Extracting Month from a Date Object in JavaScript
The code creates a Date object for October 15, 1996. It then uses getMonth() to extract the month, which is zero-indexed (October corresponds to 9), and prints it to the console.
// Creating a Date Object
let DateObj = new Date('October 15, 1996 05:35:32');
// Month from above Date Object is
// Being extracted using getMonth()
let months = DateObj.getMonth();
// Printing month.
console.log(months);
Output
9
Example 2: Invalid Date Input in Date getMonth() Method
Here the date of the month should lie between 1 to 31 because no date can have a month greater than 31. That is why it returns NaN i.e, Not a Number if the month in the Date object is greater than 31.
// Creating a Date Object
let DateObj = new Date('October 33, 1996 05:35:32');
// Month from above Date Object is being
// Extracted using getMonth()
let months = DateObj.getMonth();
// Printing month.
console.log(months);
Output
NaN
Example 3: Providing no parameter in Date getMonth() Method
If nothing as a parameter is given, it returns the current month. It is returning 2 as March is the third month and months are zero-indexed in JavaScript.
// Creating a Date Object
let DateObj = new Date();
// Month from above Date Object is being
// Extracted using getMonth()
let months = DateObj.getMonth();
// Printing month.
console.log(months);
Output
2
