Date calculations often depend on the country and wxDateTime allows to set the
-country whose conventions should be used using
+country whose conventions should be used using
\helpref{SetCountry}{wxdatetimesetcountry}. It takes one of the following
values as parameter:
Different parts of the world use different conventions for the week start.
In some countries, the week starts on Sunday, while in others -- on Monday.
The ISO standard doesn't address this issue, so we support both conventions in
-the functions whose result depends on it (\helpref{GetWeekOfYear}{wxdatetimegetweekofyear} and

These functions carry out \helpref{arithmetics}{tdatearithm} on the wxDateTime
objects. As explained in the overview, either wxTimeSpan or wxDateSpan may be
arguments.
Also, both {\tt Add()} and {\tt Subtract()} have both const and non-const
-version. The first one returns a new obejct which represents the
+version. The first one returns a new object which represents the
sum/difference of the original one with the argument while the second form
modifies the object to which it is applied. The operators $-=$ and $+=$ are
defined to be equivalent to the second forms of these functions.
