How to Correct getMonth() Function to Return Correct Month in JavaScript?

getMonth() Function in JavaScript Returns Previous Month

In JavaScript, the getMonth() method returns the month of the specified date, starting from 0 (January). However, when used with dates formatted as "Sun Jul 7 00:00:00 EDT 2013," it can provide the previous month instead of the expected one.

This is because the getMonth() method assumes that the month value starts from 0 instead of 1. Therefore, when you call d1.getMonth() on the provided date, it returns 6 (representing July), but you may expect it to return 7.

To resolve this issue, you can simply add 1 to the result of getMonth() to get the correct month number. For example:

var d1 = new Date("Sun Jul 7 00:00:00 EDT 2013");
d1.getMonth() + 1; //returns 7

By adding 1, you effectively convert the month value from the 0-based indexing to the 1-based indexing, which is commonly used for calendar months. This will ensure that getMonth() returns the correct month for dates formatted in the specified format.
