I have 2 xsl variables (currentBillDate and lastBillDate), both having access to dates in format of yyyy-mm-dd.
How can I calculate the number of days in between both days?
Example: 2006-08-28 - 2006-11-06
I tried it this way but it kept giving me NaN
<xsl:value-of select="$currentBilldate - $lastBillDate" />
Any help would be greatly appreciated
