Calculates the difference (in months) between two dates.
|
|
|
|
- Use `Date.prototype.getFullYear()` and `Date.prototype.getMonth()` to calculate the difference (in months) between two `Date` objects.
|
|
|
|
```js
|
|
const getMonthsDiffBetweenDates = (dateInitial, dateFinal) =>
|
|
Math.max(
|
|
(dateFinal.getFullYear() - dateInitial.getFullYear()) * 12 +
|
|
dateFinal.getMonth() -
|
|
dateInitial.getMonth(),
|
|
0
|
|
);
|
|
```
|
|
|
|
```js
|
|
getMonthsDiffBetweenDates(new Date('2017-12-13'), new Date('2018-04-29')); // 4
|
|
```
