The return value is positive if &lt;code&gt;date2&lt;/code&gt; comes &#039;&#039;after&#039;&#039; &lt;code&gt;date1&lt;/code&gt;, and is negative if &lt;code&gt;date2&lt;/code&gt; comes &#039;&#039;before&#039;&#039; &lt;code&gt;date1&lt;/code&gt; (i.e. the template computes &lt;code&gt;date2 - date1&lt;/code&gt;). <br /> <br /> ===Usage===<br /> If two dates supplied, the template calculates the difference between them, in days. If only one date is supplied, then the supplied date is calculated against the current date. If no dates are supplied, the template calculates the number of days from the start of the [[Wikipedia:Julian epoch|Julian epoch]] to the current date. If an invalid date is supplied, then the text is returned unaltered.<br /> <br /> The inputted dates may be in any format understood by the &lt;code&gt;#time:&lt;/code&gt; parser function. (e.g. &lt;code&gt;July 18, 2008&lt;/code&gt;, &lt;code&gt;18 July 2008&lt;/code&gt; and &lt;code&gt;2008-07-18&lt;/code&gt; are all valid.) Hours, minutes and seconds can likewise be inputted.<br /> <br /> This template can be used for dates from 1 January 1970 onwards only.<br /> <br /> ===Examples===<br /> :{| class=&quot;wikitable&quot;<br /> !
