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

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.

+Set the date to the given \arg{weekday} in the week number \arg{numWeek} of the

+Note that the returned date may be in a different year than the one passed to
+this function because both the week $1$ and week $52$ or $53$ (for leap years)
+contain days from different years. See
+\helpref{GetWeekOfYear}{wxdatetimegetweekofyear} for the explanation of how the
