Mike, there is no harm in setting up an annual calendar and adjusting for weather if/as necessary. If you are adjusting for weather, and you realize you need to have that latitude, why plan a year in advance only to have the plan change a week ahead of the scheduled date? Given the variation in weather around that time of year, it just doesn't make sense to me to plan that far ahead only to change it when you get close. I am completely willing to put a date on the calendar as long as everyone realizes that it is subject to change.
