[rules-users] Date for 2 years ago

[Brian Enderle]

I need to code a rule which checks that the begin date for an object is at 
least two years ago (from todays date).  Is there an easy way to code this 
within Drools rule, something like:

when
   Reference(fromDate > (todaysDate - 2 years))
then
   <Output error>
end

Thanks in advance,
Brian Enderle
