Calculates the difference (in days) between two dates.
|
|
|
|
- Subtract the two `Date` objects and divide by the number of milliseconds in a day to get the difference (in days) between them.
|
|
|
|
```js
|
|
const getDaysDiffBetweenDates = (dateInitial, dateFinal) =>
|
|
(dateFinal - dateInitial) / (1000 * 3600 * 24);
|
|
```
|
|
|
|
```js
|
|
getDaysDiffBetweenDates(new Date('2017-12-13'), new Date('2017-12-22')); // 9
|
|
```
