Calculates the difference (in hours) between two dates.
|
|
|
|
- Subtract the two `Date` objects and divide by the number of milliseconds in an hour to get the difference (in hours) between them.
|
|
|
|
```js
|
|
const getHoursDiffBetweenDates = (dateInitial, dateFinal) =>
|
|
(dateFinal - dateInitial) / (1000 * 3600);
|
|
```
|
|
|
|
```js
|
|
getHoursDiffBetweenDates(
|
|
new Date('2021-04-24 10:25:00'),
|
|
new Date('2021-04-25 10:25:00')
|
|
); // 24
|
|
```
