% \maketitle
% \begin{abstract}
%   The package \pkg*{scrdate} defines some macros
%   to handle the name of the day and the date in ISO format.
%
%   Up to version 3.49.2 it was part of the \KOMAScript{} collection. Since
%   version 3.50 it is a standalone package.
% \end{abstract}
% \tableofcontents
%
% \section{User Manual}
%
% Originally, the \pkg*{scrdate} package  could only give the day of the
% week for the current date. Nowadays, it offers this and more for any date in
% the Gregorian calendar.
%
% \DescribeCommand\CenturyPart
% \DescribeCommand\DecadePart
% The command \cs{CenturyPart}\marg{year} returns the value of the century
% digits\,---\,thousands and hundreds\,---\,of a \meta{year}. The command
% \cs{DecadePart}\marg{year} command, on the other hand, gives the value of
% the remaining digits, i.\,e. the tens and the units. The \meta{year} can have
% any number of digits. You can assign the value directly to a counter or use it
% for calculations with \cs{numexpr}\dots\cs{relax} or \cs{inteval}. To
% output it as an Arabic number, you should prefix it with \cs{the}.
%
% \begin{labeling}{Example:}
% \item[Example:]
%   You want to calculate and print the century of the current year.
%\begin{verbatim}
%   The year \the\year\ is year \the\DecadePart{\year} of the
%   \engordnumber{\numexpr \CenturyPart{\year}+1\relax} century.
%\end{verbatim}
%   The result would be:
%   \begin{quote}
%     The year \the\year\ is year \the\DecadePart{\year} of the
%     \engordnumber{\inteval{\CenturyPart{\year}+1}} century.
%   \end{quote}
%   This example uses the \pkg{engord} package.
% \end{labeling}
%
% Note that the counting method used here treats the year 2000 as
% year~0\,---\,and therefore the first year\,---\,of the 21st~century.  If
% necessary, however, you can make a correction with \cs{numexpr} or
% \cs{inteval}, as shown for the ordinal number in the example.
%
% \DescribeCommand\DayNumber
% \DescribeCommand\ISODayNumber
% These two commands return the value of the day-of-the-week number for any
% date. They differ only in the method of specifying the date. While the
% \cs{DayNumber}\linebreak[1]\marg{year}\linebreak[1]\marg{month}\linebreak[1]\marg{day}
% command requires the \meta{year}, \meta{month}, and \meta{day} as separate
% parameters, the \cs{ISODayNumber}\marg{ISO date} command expects an
% \meta{ISO date} as a single argument, \meta{ISO date}, using the ISO notation
% \meta{year}\texttt{-}\meta{month}\texttt{-}\meta{day}. It does not matter if
% the \meta{month} or \meta{day} have one or two digits. You can use the
% result of both commands to assign directly to a counter or for calculations
% using \cs{numexpr}\dots\cs{relax} or \cs{inteval}. To print it as an Arabic
% number, you should prefix it with \cs{the}.
%
% \begin{labeling}{Example:}
% \item[Example:]
%   You want to know the number of the day of the week of the 1st~May~2027.
%\begin{verbatim}
%   The 1st~May~2027 has \the\ISODayNumber{2027-5-1}
%   as the number of the day of the week.
%\end{verbatim}
%   The result will be:
%   \begin{quote}
%     The 1st~May~2027 has \the\ISODayNumber{2027-5-1}
%     as the number of the day of the week.
%   \end{quote}
% \end{labeling}
% The days of the week are numbered as follows: Sunday\,=\,0, Monday\,=\,1,
% Tuesday\,=\,2, Wednesday\,=\,3, Thursday\,=\,4, Friday\,=\,5, and
% Saturday\,=\,6.
%
% \DescribeCommand\DayNameByNumber
% \DescribeCommand\DayName
% \DescribeCommand\ISODayName
% Usually you are less interested in the number of the day of the week than in
% its name. Therefore, the command \cs{DayNameByNumber}\marg{number of the day
% of the week} returns the name of the day of the week corresponding to a
% \meta{number of the day of the week}. This number can be the result, for
% example, of \cs{DayNumber} or \cs{ISODayNumber}. The two commands
% \cs{DayName}\marg{year}\marg{month}\marg{day} and \cs{ISODayName}\marg{ISO
% date} directly return the name of the day of the week of a given date.
%
% \begin{labeling}{Example:}
% \item[Example:] You want to know the name of the day of the week of the
%   24th~December~2027.
%\begin{verbatim}
%   Please pay by \ISODayName{2027-12-24},
%   24th~December~2027 the amount of \dots.
%\end{verbatim}
%   The result will be:
%   \begin{quote}
%     Please pay by \ISODayName{2027-12-24},
%     24th~December~2027 the amount of \dots.
%   \end{quote}
% \end{labeling}
%
% Once again, it is particularly worth noting that you can perform
% calculations, to a certain extent:
% \begin{labeling}{Example:}
% \item[Example:] You want to know the names of the day of the week 12~days
%   from now and 24~days before the 24th~December~2027.
%\begin{verbatim}
%   In 12~days, the name of the day of the week will be
%   \DayNameByNumber{\DayNumber{\year}{\month}{\day}+12}, and
%   24~days before the 24th~December~2027 it will be
%   \DayNameByNumber{\ISODayNumber{2027-12-24}-24}, while two
%   weeks and three days after a Wednesday will be a
%   \DayNameByNumber{3+2*7+3}.
%\end{verbatim}
%   The result could be, for example:
%   \begin{quote}
%     In 12~days, the name of the day of the week will be
%     \DayNameByNumber{\DayNumber{\year}{\month}{\day}+12}, and
%     24~days before the 24th~December~2027 it will be
%     \DayNameByNumber{\ISODayNumber{2027-12-24}-24}, while two
%     weeks and three days after a Wednesday will be a
%     \DayNameByNumber{3+2*7+3}.
%   \end{quote}
% \end{labeling}
%
% \DescribeCommand{\ISOToday}
% \DescribeCommand{\IsoToday}
% \DescribeCommand{\todaysname}
% \DescribeCommand{\todaysnumber}
% In the previous examples, the current date was always specified cumbersomely
% using the \TeX{} registers \cs{year}, \cs{month}, and \cs{day}. The
% \cs{ISOToday} and \cs{IsoToday} commands directly return the current date in
% ISO-notation. These commands differ only in the fact that \cs{ISOToday}
% always outputs a two-digit month and day, while \cs{IsoToday} outputs
% single-digit numbers for values less than 10. The \cs{todaysname} command
% directly returns the name of the current day of the week, while
% \cs{todaysnumber} returns the number of the current day of the week. You can
% find more information about using this value in the explanations of
% \cs{DayNumber} and \cs{ISODayNumber} above.
%
% \begin{labeling}{Example:}
% \item[Example:] I want to show you on what day of the week this document was
%   typeset:
%\begin{verbatim}
%   This document was created on a \todaysname.
%\end{verbatim}
%   This will result, for example, in:
%   \begin{quote}
%     This document was created on a \todaysname.
%   \end{quote}
% \end{labeling}
%
% For languages that have a case system for nouns, note that the package
% cannot decline words. The terms are given in the form appropriate for
% displaying a date in a letter, which is the nominative singular for the
% currently supported languages. Given this limitation, the example above will
% not work correctly if translated directly into some other languages.
%
% The names of the weekdays in \pkg*{scrdate} all have initial capital
% letters. If you need the names completely in lower case, for example because
% that is the convention in the relevant language, simply wrap the command
% with the \LaTeX{} \cs{MakeLowercase} command:
%\begin{verbatim}
%   \MakeLowercase{\todaysname}
%\end{verbatim}
% This converts the whole argument into lower-case letters. Of course, you can
% also do this for \cs{DayNameByNumber}, \cs{DayName}, and \cs{ISODayName}
% commands described above.
%
%
% \DescribeCommand{\nameday}
% Just as you can directly modify the output of \cs{today} with \cs{date}, so
% you can change the output of \cs{todaysname} to \meta{name} with
% \cs{nameday}\marg{name}.
% \begin{labeling}{Example:}
% \item[Example:] You change the current date to a fixed value using
%   \cs{date}. You are not interested in the actual name of the day, but want
%   only to show that it is a workday. So you write:
%\begin{verbatim}
%   \nameday{workday}
%\end{verbatim}
%   After this, the previous example will result in:
%   \begin{quote}
%     This document was created on a workday.
%   \end{quote}
% \end{labeling}
% There's no corresponding command to change the result of
% \cs{ISOToday} or \cs{IsoToday}.
%
%
% \DescribeCommand\newdaylanguage
% Currently the \pkg*{scrdate} package recognizes the following languages:
% \begin{itemize}\setlength{\itemsep}{.5\itemsep}
% \item Croatian (\texttt{croatian}),
% \item Czech (\texttt{czech}),
% \item Danish (\texttt{danish}),
% \item Dutch (\texttt{dutch}),
% \item English (\texttt{american}, \texttt{australian}, \texttt{british},
%   \texttt{canadian}, \texttt{english}, \texttt{UKenglish}, and
%   \texttt{USenglish}),
% \item Finnish (\texttt{finnish}),
% \item French (\texttt{french}),
% \item German (\texttt{austrian}, \texttt{german}, \texttt{naustrian},
%   \texttt{ngerman}, \texttt{nswissgerman}, and \texttt{swissgerman}),
% \item Italian (\texttt{italian}),
% \item Norwegian (\texttt{norsk}),
% \item Polish (\texttt{polish}),
% \item Slovak (\texttt{slovak}),
% \item Spanish (\texttt{spanish}),
% \item Swedish (\texttt{swedish}).
% \end{itemize}
% You can also configure it for additional languages. To do so, the first
% argument of
% \cs{newdaylanguage}\linebreak[1]\marg{language}\linebreak[1]\marg{Monday}\linebreak[1]\marg{Tuesday}\linebreak[1]\marg{Wednesday}\linebreak[1]\marg{Thursday}\linebreak[1]\marg{Friday}\linebreak[1]\marg{Saturday}\linebreak[1]\marg{Sunday}
% is the name of the language, and the other arguments are the names of the
% corresponding days of the week.
%
% In the current implementation, it does not matter whether you load
% \pkg*{scrdate} before or after \pkg{ngerman}, \pkg{babel}, or similar
% packages. In each case the correct language will be used provided it is
% supported.
%
% To be more precise, as long as you select a language in a way that is
% compatible with \pkg{babel}, \pkg*{scrdate} will use the correct
% language. If this is not the case, you will get (US) English names.
%
% Of course, if you create definitions for a language that was previously
% unsupported, please mail them to the author of \pkg*{scrdate} or add a
% ticket to the issue tracker. There is a good chance that future versions of
% \pkg*{scrdate} will add support for that language.%
