<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>This class is a "logical time span" and is useful for implementing program logic for such things as "add one month to the date" which, in general, doesn't mean to add 60*60*24*31 seconds to it, but to take the same date the next month (to understand that this is indeed different consider adding one month to Feb, 15 – we want to get Mar, 15, of course). </p>
<p>When adding a month to the date, all lesser components (days, hours, ...) won't be changed unless the resulting date would be invalid: for example, Jan 31 + 1 month will be Feb 28, not (non-existing) Feb 31.</p>
<p>Because of this feature, adding and subtracting back again the same <a class="el" href="classwx_date_span.html" title="This class is a "logical time span" and is useful for implementing program logic for such things as...">wxDateSpan</a> will <b>not</b>, in general, give back the original date: Feb 28 - 1 month will be Jan 28, not Jan 31!</p>
<p><a class="el" href="classwx_date_span.html" title="This class is a "logical time span" and is useful for implementing program logic for such things as...">wxDateSpan</a> objects can be either positive or negative. They may be multiplied by scalars which multiply all deltas by the scalar: i.e. 2*(1 month and 1 day) is 2 months and 2 days. They can be added together with <a class="el" href="classwx_date_time.html" title="wxDateTime class represents an absolute moment in time.">wxDateTime</a> or <a class="el" href="classwx_time_span.html" title="wxTimeSpan class represents a time interval.">wxTimeSpan</a>, but the type of result is different for each case.</p>
<dl class="section warning"><dt>Warning</dt><dd>If you specify both weeks and days, the total number of days added will be 7*weeks + days! See also <a class="el" href="classwx_date_span.html#a84bf5822fbcb14d85d3c170d0b40d1ea" title="Returns the combined number of days in this date span, counting both weeks and days.">GetTotalDays()</a>.</dd></dl>
<p>Equality operators are defined for wxDateSpans. Two wxDateSpans are equal if and only if they both give the same target date when added to <b>every</b> source date. Thus wxDateSpan::Months(1) is not equal to wxDateSpan::Days(30), because they don't give the same date when added to Feb 1st. But wxDateSpan::Days(14) is equal to wxDateSpan::Weeks(2).</p>
<p>Finally, notice that for adding hours, minutes and so on you don't need this class at all: <a class="el" href="classwx_time_span.html" title="wxTimeSpan class represents a time interval.">wxTimeSpan</a> will do the job because there are no subtleties associated with those (we don't support leap seconds).</p>
