I want to find a business calendar that is made up of 13 periods, each 4
weeks long. It can be in any Microsoft program. I would prefer a program that
has a flexible start date so that you can enter the first date and it will
calculate the rest of the calendar. Since this calendar has 364 days it
gradually drifts away from a normal start date of Jan 1. Businesses therefore
make periodic adjustments to the start date to bring it back in line with the
normal Jan 1.
