<h1>DATEDIF Function</h1>
|
|
<p>The <b>DATEDIF</b> function is one of the <a href="../UsageInstructions/InsertFunction.htm#datetime" onclick="onhyperlinkclick(this)">date and time functions</a>. It is used to return the difference between two date values (start date and end date), based on the interval (unit) specified.</p>
|
|
<h3>Syntax</h3>
|
|
<p><b><em>DATEDIF(start_date, end_date, unit)</em></b></p>
|
|
<p>The <b>DATEDIF</b> function has the following arguments:</p>
|
|
<table style="width: 40%">
|
|
<tr>
|
|
<th style="background-color: #f4f4f4" width="150ch"><b>Argument</b></th>

|
|
<td><b><em>unit</em></b></td>
|
|
<td>The specified interval. The possible values are listed in the table below.</td>
|
|
</tr>
|
|
</table>
|
|
<p>The <b><em>unit</em></b> argument can be one of the following:</p>
|
|
<table style="width: 40%">
|
|
<tr>
|
|
<th style="background-color: #f4f4f4"><b>Unit</b></th>
|
|
<th style="background-color: #f4f4f4"><b>Interval Explanation</b></th>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>Y</em></b></td>
|
|
<td>The number of complete years.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>M</em></b></td>
|
|
<td>The number of complete months.</td>
|
|
</tr>
|
|

|
|
<td><b><em>D</em></b></td>

|
|

|
|
<td>The difference between the days (months and years are ignored).</td>
|
|
</tr>
|
|
<tr>
|
|

|
|

|
|

|
|
<td>The difference between the days (years are ignored).</td>
|
|
</tr>
|
|

<h3>Notes</h3>
|
|
<p>If the <b><em>start_date</em></b> is greater than the <b><em>end_date</em></b>, the result will be #NUM!.</p>
|
|
<p><a href="../UsageInstructions/InsertFunction.htm#applyfunction" onclick="onhyperlinkclick(this)">How to apply</a> the <b>DATEDIF</b> function.</p>
|
|
<h3>Examples</h3>
|
|
<p>There are three arguments: <em>start-date</em> = <b>A1</b> = <b>3/16/2018</b>; <em>end-date</em> = <b>A2</b> = <b>9/16/2018</b>; <em>unit</em> = <b>"D"</b>. So the function returns the difference between two dates in days.</p>
