Hi Vivek,
1)
If you want to do the calculation in XML (in screen widgets), I would
suggest calling a java method like that:
<call-class-method class-name="org.ofbiz.base.util.UtilDateTime OR whatever
class that contains the method" method-name="methodName"
ret-field="resultVariable">
<field field="date1" type="java.sql.Timestamp"/>
<field field="date2" type="java.sql.Timestamp"/>
</call-class-method>
2)
If you want to do it in ftl, just subtract the 2 dates and divide by
1000*60*60*24. Make sure the dates are both correctly formatted.
Take a look at that:

Hope that helps.
