Yom HaShoah is Sunday night until Monday night.
I remember going through a cemetery not long ago in arizona (I love going through cemeteries) and there was a tombstone of a man who died in 2010. On the back of his tombstone are the names of 9 family members he lost in the Holocaust. Five siblings, mother, father, 2 grandparents. It is said that 1 in 3 european jews survived. He was 1 in 10 who survived.
