I would not call this 'validation' as that term is normally kept for checking data being saved in the db. What you are doing here is just checking that the parameters to the controller action are ok before accepting the action. In that case I would say it is fine in the controller to check the dates before allowing the action. The javascript method is probably arguably even better as it avoids the round trip to the server. I would probably not bother with the additional complication however, it is not a regular occurrence (presumably) and even if you validate in javascript you will still have to check in the controller in case the user has javascript disabled.
