How to get months between two dates in javascript?

Hi Friends 👋,

Welcome To Infinitbility! ❤️

To get months between two dates,

1. Use the getMonth() method to get the months of both dates, and subtract them to get the difference of months
2. Use the getFullYear() method to get the years of both dates, and subtract them to get the difference of years
3. Multiply the year difference by 12 and return the sum.

It will return your difference of dates in months.

The getMonth() method returns the month on the specified date according to local time, as a zero-based value (where zero indicates the first month of the year).

The getFullYear() method returns the year of the specified date according to local time.

Today, I’m going to show How do I get months between two dates in javascript, here I will use the javascript getMonth() method and getFullYear() method to get difference numbers of months.

  return (endDate.getMonth() - startDate.getMonth() + 12 * (endDate.getFullYear() - startDate.getFullYear()));
}

// 👇️ 2
console.log(getMonths(new Date('2022-01-15'), new Date('2022-03-16')));
