%\maketitle
%
%\begin{abstract}
%This is the Finnish language module for the \sty{datetime2}
%package. If you want to use the settings in this module you must
%install it in addition to installing \sty{datetime2}. If you use
%\sty{babel} or \sty{polyglossia}, you will need this module to
%prevent them from redefining \cs{today}. The \sty{datetime2}
% \opt{useregional} setting must be set to "text" or "numeric"
% for the language styles to be set.
% Alternatively, you can set the style in the document using
% \cs{DTMsetstyle}, but this may be changed by \cs{date}\meta{language}
% depending on the value of the \opt{useregional} setting.
% Currently there is only a regionless style.

%\section{Introduction}
%\label{sec:intro}
%This module defines the styles "finnish" and "finnish-numeric".
%The "finnish" style will automatically be set if the \opt{useregional}
%option is set to \texttt{text}, and the "finnish-numeric" style is automatically
%set if the \opt{useregional} option is set to \texttt{numeric}.
%
%There are a number of settings provided that can be used in
%\cs{DTMlangsetup} to modify the date-time style. These are:
%
%\begin{description}
%\item[\opt{dowdaysep}] The separator between the day of week name and the
%day of month number. This defaults to \cs{space}. Ignored if the
%\opt{showdow} option is \texttt{false}.
%
%\item[\opt{daymonthsep}] The separator between the day and the month
%name in the \texttt{finnish} style. This defaults to \cs{space}.
%
%\item[\opt{monthyearsep}] The separator between the month name and year
% in the \texttt{finnish} style. This defaults to \cs{space}.
%
%\item[\opt{datesep}] The separator between the date numbers in the
%"finnish-numeric" style. This defaults to "." (period).
%
%\item[\opt{timesep}] The separator between the hours and minutes in both
%"finnish" and "finnish-numeric" styles. This defaults to "." (period).
%
%\item[\opt{datetimesep}] The separator between the date and time for the
%full date-time format (as used by \cs{DTMdisplay}) for both the
%"finnish" and "finnish-numeric" styles. This defaults
%to \cs{space}.
%
%\item[\opt{timezonesep}] The separator between the time and zone for the
%full date-time format (as used by \cs{DTMdisplay}) for both the
%"finnish" and "finnish-numeric" styles. This defaults
%to \cs{space}.
%
%\item[\opt{abbr}] This is a~boolean key. If "true", the month (and week
%day name if shown) is abbreviated for the "finnish" style. The default is "false".
%
%\item[\opt{mapzone}] This is a~boolean key. If "true" the time zone
%mappings are applied. (The default is \texttt{true}.) The "finnish"
% and "finnish-numeric" styles set the mappings EET
%(\utc{02}{00}) and EEST (\utc{03}{00}).
%Other time zone mappings that have previously been set
%(for example, by another regional style) will remain unchanged
%unless you redefine \cs{DTMresetzones} to reset or unset them.
%
%\item[\opt{showdayofmonth}] A boolean key that determines whether
%or not to show the day of the month. The default value is "true".
%If "false" the day-month separator is also omitted.
%
%\item[\opt{showyear}] A boolean key that determines whether
%or not to show the year. The default value is "true". If "false"
%the month-year separator is also omitted.
%\end{description}
%
%The above settings are specific to this module. In addition, the
%\opt{showdow} boolean option provided by the \sty{datetime2} package is
%checked to determine whether or not to show the day of the
%week in the "finnish" style. The \opt{showdate}, \opt{showzone},
%\opt{showseconds} and \opt{showzoneminutes} settings of \sty{datetime2}
%are honoured.
