Answer: In your zone 6A location, or the colder part of zone 6, possibly even as cold as zone 5 if it is windy and exposed site, I would suggest waiting until spring to plant any evergreens. The reason is that they continue to lose moisture through their foliage all winter and once the soil is frozen they are unable to replace it. Planting in spring allows them all spring, summer and fall to become rooted and established before that stress. You can plant as early as the ground can be worked, meaning it is not frozen and not too muddy and you may want to work in advance with your local professional nursery staff to obtain the size you need in that quantity. Good luck with your planting.
