pm_dateTime::getDateAfter Interface Reference

Generate and return the date in the Gregorian Calendar that appears after the input date. More...

Detailed Description

Generate and return the date in the Gregorian Calendar that appears after the input date.

Returning the correct result requires taking into account the possibility of leap years.

Parameters

[in]	values	: The input contiguous array of shape (:), of size 3 or larger, of type integer of default kind IK, containing the [year, month, day] triple of the Gregorian calendar. For the current local date, this triple can be obtained from the Fortran intrinsic date_and_time() or getDateTime(). Only the first three elements (values(1:3)) are used to compute the output. The ability to pass longer vectors as input is to allow the output values(1:8) of various functionalities of this module to be passed directly to the procedures under this generic interface. (optional. It can be present if and only if all other input arguments are missing.)
[in]	year	: The input scalar, or array of the same shape as other array-like arguments, of type integer of default kind IK, containing the year of the Gregorian calendar. (optional. It can be present if and only if the input argument values is missing.)
[in]	month	: The input scalar, or array of the same shape as other array-like arguments, of type integer of default kind IK, containing the month of the Gregorian calendar. (optional. It must be present if and only if the input argument year is present.)
[in]	day	: The input scalar, or array of the same shape as other array-like arguments, of type integer of default kind IK, containing the day of the Gregorian calendar. (optional. It must be present if and only if the input argument month is present.)

Returns

dateAfter : The output vector of size 3 of type integer of default kind IK, containing the date in the Gregorian Calendar in the format [year, month, day] that appears after the input date.

Possible calling interfaces ⛓

use pm_dateTime, only: getDateAfter
integer(IK) :: dateAfter(3)
 
dateAfter(1:3) = getDateAfter() ! current date is used.
dateAfter(1:3) = getDateAfter(values(1:3)) ! values = [year, month, day]
dateAfter(1:3) = getDateAfter(year, month, day)
!

Warning

The size of the input argument values(:) must be at least 3 and at most 8.
The input values for the year, month, and day must be valid values.
The input month must be a number between 1 and 12.
The input day must be a number between 1 and 31.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.

The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds.

Remarks

The procedures under discussion are elemental. The procedures under this generic interface are non-elemental when the input argument values(:) is present.
