by July 3 - August 11
The dog days or dog days of summer are the hot, sultry days of summer.
They were historically the period following the heliacal rising of the star system Sirius (known colloquially as the "Dog Star"), which Hellenistic astrology connected with heat, drought, sudden thunderstorms, lethargy, fever, mad dogs, and bad luck.
They are now taken to be the hottest, most uncomfortable part of summer in the Northern Hemisphere.
This effect of the combination of Sirius' light with the Sun's was understood to have an effect on plants, animals, and women, as well as men.
