DOG DAYS OF SUMMER
The term “dog days of summer” has to do with the night sky. Sirius, the brightest star in the summer sky, is in the constellation called Canis Major, which means “big dog.” During the days from early July to mid-August, Sirius is in conjunction with the sun. This means that it rises and sets, and is in alignment with, the sun. Ancient people thought that the heat from the sun was being joined by the heat from Sirius, causing much warmer days. They called this time of year the “dog days,” after the constellation Canis Major.
