CAN ASPERGER'S PEOPLE KEEP DIARIES?!! I CAN'T!

Hi, I was diagnosed in 2010 with Asperger's, at the age of 52.  I once heard a snatch of someone on the radio saying 'we Asperger's don't do diaries.'  I have appalling problems putting the appointments on the right month of the diary and the right date.  I try to join zoom lessons on the wrong day etc etc!  Does anyone know of any good books which explain about our problems with time?
