Detailed Description

Generate and return the week year corresponding to the ISO 8601 Week Date triple [week year, week number, week day] equivalent of the input Gregorian date and time values(1:3) or (year, month, day) triple.

See the documentation of getWeekDate for more information on the ISO week date system.

Note: When all input arguments are missing, the procedures under this generic interface return the current ISO Week Year.

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: weekYear : The output scalar (or array of the same rank as year, month, or day) of shape(1:3)of typeinteger` of default kind IK containing the ISO 8601 Week Year.

Possible calling interfaces ⛓

: use pm_dateTime, only: getWeekYear

integer(IK) :: WeekDate(3)

WeekDate(1:3) = getWeekYear() ! always impure.

WeekDate(1:3) = getWeekYear(values(1:3))

WeekDate(1:3) = getWeekYear(year, month, day)

pm_dateTime
This module contains classes and procedures for computing, manipulating, and styling dates and times.
Definition: pm_dateTime.F90:308

Warning: The size of the input argument values(:) must be at least 3 and at most 8.
This condition is 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. The procedures under this generic interface are always impure when all input arguments are missing.

Remarks: The procedures under this generic interface are elemental when the input arguments year, month, day are present.
