|
|
* Get the number of hours between the given dates.
|
|
*
|
|
* @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).

|
*
|
|
* @param dateLeft - The later date
|
|
* @param dateRight - The earlier date
|
|
* @param options - An object with options.
|
|
*
|
|
* @returns The number of hours
|
|
*
|
|
* @example
|
|
* // How many hours are between 2 July 2014 06:50:00 and 2 July 2014 19:00:00?
|
|
* const result = differenceInHours(
|
|
* new Date(2014, 6, 2, 19, 0),
|
|
* new Date(2014, 6, 2, 6, 50)
