schematic calendar, schematic year, schematic month,
The fact that certain stars had become connected with the schematic year of 12 months x 30 days each greatly assisted the development of the reduction of the zodiac to 12 divisions. The calendar was schematic because of the fact that the year does not consist of exactly 360 days. This made it necessary to add an extra 13th month now and then. The periodic intercalation of a 13th lunar month was done to keep the lunar calendar in line with the seasons. It was not based on solar observations.) (This theoretical division of the year into 12 months of 30 days each is indicated as dating back to the Old Babylonian Period circa 1800 BCE.
