What is the origin of this scorching phrase?
The "Dog Days" of summer, typically lasting from July 3rd to August 11th, are synonymous with hot, humid weather. But why are they called that? The answer lies in the ancient world.
The Heat is On: Sirius and Summer
In ancient Greece and Rome, this period was associated with drought, bad luck, and even madness – both for humans and dogs. Today, it's simply the peak of summer heat. This timing coincides with the heliacal rising of Sirius, the brightest star in the sky after the Sun.
Sirius, part of the constellation Canis Major (the Greater Dog), was believed to contribute to the scorching temperatures. The combined heat of Sirius and the Sun was thought to be the cause of summer's sweltering weather. Interestingly, for the Egyptians, Sirius's rising marked the Nile River's flood season, a welcome event that brought fertile soil.
Fact or Fiction?
While Sirius's appearance doesn't directly affect Earth's weather, its association with the hottest part of the year has kept the lore alive.
The exact dates of the Dog Days can vary, but they generally fall in mid-to-late summer. The Old Farmer's Almanac sets them from July 3rd to August 11th.
Sirius: The Dog Star
Sirius is so bright it can sometimes be seen during the day. Its position in the constellation Canis Major earned it the nickname "the Dog Star."
The Egyptians revered Sirius, linking its rising to the Nile's flood. In contrast, the Greeks and Romans saw it as a harbinger of misfortune. Surprisingly, a 2009 study found evidence to support the idea that infection rates increase during the Dog Days.
The Dog Days in Literature and Popular Culture
The Dog Days of Summer have been referenced in numerous works of literature and popular culture. For example, in Shakespeare's Henry IV, Part I, Falstaff refers to the "dog days of summer." The phrase has also been used in songs, movies, and television shows.
