Dog Days of Summer

The expression ” dog days of summer ” originated in ancient Rome. The Romans noticed that between July 3 -August 11, the star Sirius joined the sun at sunrise, appearing to become one. They believed this added to the extra warmth in the hottest days of the year. Sirius, the brightest star in the sky after our sun, belongs to the constellation Canis Major, known as Big Dog or the Dog Star. Because the earth wobbles on its axis these days are no longer precise, in America Sirius doesn’t “join” the sun until August 4 – Sept. 11. The hottest days of the year are still referred to as the “dog days”.
