|
* @description
|
|
* Get the number of calendar days between the given dates. This means that the times are removed
|
|
* from the dates and then the difference in days is calculated.
|
|
*
|
|
* @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
|
|
*
|
|
* @returns The number of calendar days
|
|
*
|
|
* @example
|
|
* // How many calendar days are between
|
|
* // 2 July 2011 23:00:00 and 2 July 2012 00:00:00?
|
|
* const result = differenceInCalendarDays(
|
|
* new Date(2012, 6, 2, 0, 0),
|
|
* new Date(2011, 6, 2, 23, 0)
|
|
* )
|
|
* //=> 366
|
|
* // How many calendar days are between
|
|
* // 2 July 2011 23:59:00 and 3 July 2011 00:01:00?
|
|
* const result = differenceInCalendarDays(
|
|
* new Date(2011, 6, 3, 0, 1),
|
|
* new Date(2011, 6, 2, 23, 59)
|
|
* )
|
|
* //=> 1
