To summit during a full moon, a 7-day climb should start 5 days
prior to the full moon date. It is not necessary to summit on
the exact full moon date to take advantage of moonlight. A summit
on the day before or day after is also beneficial.
For those who favor a less crowded climb, avoid the full moon
completely as these dates attract many climbers. Another method
of dodging crowds is to choose an "off" day of departure.
Most climbers will begin their climbs on Saturday, Sunday or Monday,
with routes lasting 6 to 7 days.
