Cooling-degree days are calculated by subtracting the daily mean temperature from a reference temperature of 65°F (18°C). In this case, the calculation would be 65°F - 83°F = -18°F. Since the temperature is above the reference temperature, there were 0 heating-degree days accumulated. To calculate the cooling-degree days, we use the absolute value of the difference, which is 18. Therefore, the answer is 18 cooling-degree days.
