We have all heard the expression, but what are they? Where did it come from?
The Dog Days of Summer are from July 3rd - August 11th each year.
It is a common misconception that the term came from the heat being not fit for a dog. It comes from the constellation Canis Major, The Greater Dog. Sirius is a part of the constellation and is the brightest visible star from any part of the Earth. The Ancient Romans. believed that since the Sun and Sirius rose and set in conjunction, that the star was giving off additional heat
This period is usually the hottest part of summer for those in the Northern Hemisphere not due to Sirius but, The Earth's tilt allowingthe Sun's rays to hit more directly.
