Day 23 is most annoying character.
This is one of the easiest ones for me. And I know quite a few of you reading this will nod your head knowingly (and sadly).

This one character single-handedly destroyed the once proud and popular soap. Where once upon a time GH was about love and romance and adventure and family, now it is about....the mob. He is the ostensible romantic lead of the show, and he is a murderer, a racketeerer, and a misogynist. He (accidentally) shot his wife in the head while she was in labor with their baby. He is currently in a storyline where his teenage daughter is realizing that he is an emotional abuser of women...and when he asks his ex-wife if she agrees with that diagnosis, she does...and we are still supposed to root for him as the romantic hero. My disgust knows no bounds. Also, the actor playing him is horrifically awful and has become a caricature of himself. Here's a scene where his fight with his wife gets so violent that his little son comes running downstairs saying "I'm not gonna let you hurt Mommy." SO ROMANTIC.
Really, "annoying" is too benign a word, but, it'll do.
