I am sorry to say your observation is wrong. Eidulb has been getting hit with monsters almost every day. It didn't get attacked like for one day over the past month. The size varies however. Mostly monsters attack in 8~9k CS. When there are more, they do hit the city with 20k CS occasionally.
I am relieved, too swamped in domestic monster battles to even notice the ones in Eidbuld. Ignorant of me..
