Dog Days Of Summer

Dog Days of Summer" has nothing to do with dogs
The official Dog Days of Summer are the days between July 3 and August 11.
This goes back to the time of the ancient Greeks. Sirius is known as the Dog Star because it marks the nose of the constellation Canus Major, Orion’s hunting dog.
Viewed from Earth, Sirius is one of the brightest stars in the galaxy of the nighttime sky during most of the year. However, by July 3, Orion and Canus Major have moved to the daytime sky.
The great thinkers among the Greeks believed that the light and heat from Sirius, the Dog Star, combined with the sun, produced the hot days of summer. After August 11, Sirius disappears from the daytime sky and becomes the brightest star in the morning just before the sun comes up. Gradually Sirius, Canus Major, and Orion move to the nighttime sky as the summer passes into fall.
