Peoria Chiropractor Things That Make You Go Hmmm…

The other day a patient came into our Peoria Chiropractor Clinic asking what we thought of the ‘dog days of summer’.  That question got me thinking, where exactly did this phrase originate?  Yes, this inquiring mind wanted to know.  And thanks to the internet, the answer is only a few keystrokes away.

According to Wikipedia the phrase dog days refers to the sultry days of summer.  In the Northern Hemisphere, the dog days of summer are most commonly experienced in the months of July and August, which typically observe the warmest summer temperatures.  The Old Farmer’s Almanac lists the traditional period of the Dog Days as the 40 days beginning July 3rd and ending August 11th, coinciding with the ancient heliacal (at sunrise) rising of the Dog Star, Sirius. According to the Farmer’s Almanac these are the days of the year with the least rainfall in the Northern Hemisphere.

So where did this term come from? In ancient times The Romans associated the hot weather with the star Sirius. They considered Sirius to be the “Dog Star” because it is the brightest star in the constellation Canis Major (Large Dog). Sirius is also the brightest star in the night sky. The term “Dog Days” was used earlier by the Greeks.

In the summer Sirius, the “dog star,” rises and sets with the sun. During late July Sirius is in conjunction with the sun, and the ancients believed that its heat added to the heat of the sun, creating a stretch of hot and sultry weather. They named this period of time, from 20 days before the conjunction to 20 days after, “dog days” after the dog star.
