Summiting on or soon after a full moon helps illuminate the landscape without using headlamps. It is very beautiful, but certainly not necessary for summiting the mountain. To summit on a full moon, you will want to start a 6-day trek 4 days before the full moon (3 days before if doing a 5-day trek).
