Rod,
You don't super bees by a calendar. You put a super in place just before the
start of a nectar flow your locale, and you add another when the first is
more than half full.
Some areas of the country have a fine Goldenrod nectar flow, and they might
add a super in late September.
Since you are new, ask other beekeepers in your area just what nectar
resources do you have and when do they bloom normally.
You are in Virginia. Surely, the nectar flows in Winchester are dramatically
different from those in Norfolk, and Bristol would be different from both
Norfolk
or Winchester.
Hope I have helped.
