<h1>DATEDIF Function</h1>
<p>The <b>DATEDIF</b> function is one of the date and time functions. It is used to return the difference between two date values (start date and end date), based on the interval (unit) specified.</p>
<p>The <b>DATEDIF</b> function syntax is:</p>
<p style="text-indent: 150px;"><b><em>DATEDIF(start-date, end-date, unit)</em></b></p>
<p><em>where</em></p>
<p style="text-indent: 50px;"><b><em>start-date</em></b> and <b><em>end-date</em></b> are two dates you wish to calculate the difference between.</p>
<p style="text-indent: 50px;"><b><em>unit</em></b> is the specified interval that can be one of the following:</p>
<table style="width: 40%">
<tr>
<td><b>Unit</b></td>
<td><b>Interval Explanation</b></td>
</tr>
<tr>
<td>Y</td>
<td>The number of complete years.</td>
</tr>
<tr>
