It says monthly. sometimes it says weekly. but in fact, it's daily. Nightly to be more precise. it's really annoying when they say "oh it's not gonna happen that often" by calling it monthly then they do it every friggin night. Why? why lie? Why test it so regularly? will it just magickally stop working one day? i know that it's important to have your emergency plan ready to be put into action at any moment, but what's so wrong with the EAS that they need to test it all the time? it's exactly like the boy who cried wolf. It only does it once a night, but still it shouldn't be doing it all the time like that.
