<a name="index-arguments_002c-of-date-construction-functions"></a>
<p>These functions take numeric arguments and give numeric results that
represent dates.  Arguments taken by these functions are:
</p>
<dl compact="compact">
<dt><var>day</var></dt>
<dd><p>Refers to a day of the month between 1 and 31.  Day 0 is also accepted
and refers to the final day of the previous month.  Days 29, 30, and
31 are accepted even in months that have fewer days and refer to a day
near the beginning of the following month.
</p>
</dd>
<dt><var>month</var></dt>
<dd><p>Refers to a month of the year between 1 and 12.  Months 0 and 13 are
also accepted and refer to the last month of the preceding year and
the first month of the following year, respectively.
</p>
</dd>
<dt><var>quarter</var></dt>
<dd><p>Refers to a quarter of the year between 1 and 4.  The quarters of the
year begin on the first day of months 1, 4, 7, and 10.
</p>
</dd>
<dt><var>week</var></dt>
<dd><p>Refers to a week of the year between 1 and 53.
</p>
</dd>
<dt><var>yday</var></dt>
<dd><p>Refers to a day of the year between 1 and 366.
</p>
</dd>
<dt><var>year</var></dt>
<dd><p>Refers to a year, 1582 or greater.  Years between 0 and 99 are treated
according to the epoch set on SET EPOCH, by default beginning 69 years
before the current date (see <a href="SET.html#SET-EPOCH">SET EPOCH</a>).
</p></dd>
</dl>

<a name="index-arguments_002c-invalid"></a>
<p>If these functions&rsquo; arguments are out-of-range, they are correctly
normalized before conversion to date format.  Non-integers are rounded
toward zero.
