Some time ago it was the birthday of one of my Mii's (not the look-a-like). She said in dutch "Today it's my birthday" when I visited her apartment, but that was all...
Here it's mentioned that a birthday seem to be a event with multiple Mii's, singing and candles, but I've saw none of it 
Why was this happening? And is it required to have access to the Mii New Tower to see the birthdays?
