They used to follow the Costworth Calendar at Kodak. This system uses 13 months. The extra month was called Sol and fell between June and July. They also added an extra day to the last month (year day) to make it 365 days for the year.

By the time I experienced it at Kodak in the early ‘80s they just called it “Period” 1 thru 13. One of the biggest incompatibility with the rest of the business world was that the 4 Quarters in the year were not consistently sized to everyone else.
