			<h1>WEEKNUM Function</h1>
			<p>The <b>WEEKNUM</b> function is one of the date and time functions. It used to return the number of the week the specified date falls within the year.</p>
			<p>The <b>WEEKNUM</b> function syntax is:</p> 
			<p style="text-indent: 150px;"><b><em>WEEKNUM(serial-value [,weekday-start-flag])</em></b></p> 
			<p><em>where</em></p> 
			<p style="text-indent: 50px;"><b><em>serial-value</em></b> is a number representing the date within the week, entered using the <a href="Date.htm" onclick="onhyperlinkclick(this)">Date</a> function or other date and time function.</p>
			<p style="text-indent: 50px;"><b><em>weekday-start-flag</em></b> is a numeric value used to determine the type of the value to be returned. It can be one of the following:</p>
			<table style="width: 40%">
				<tr>
					<td><b>Numeric value</b></td>
					<td><b>Weekday Sequence</b></td>
				</tr>
				<tr>
