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.

const getHoursDiffBetweenDates = (dateInitial, dateFinal) =>
  (dateFinal - dateInitial) / (1000 * 3600);

getHoursDiffBetweenDates(
  new Date('2021-04-24 10:25:00'),
  new Date('2021-04-25 10:25:00')
); // 24
