<prompt> Poleloana matsatsi a lintja a lehlabula a simolohile hokae?nan  <response>: Instruction in English: What is the origin of the phrase dog days of summer? . Response in English: The phrase dog days of summer refers to the hottest and most humid periods of the summer season, typically from early July to late August in the Northern Hemisphere. The origin of this phrase dates back to ancient times and is associated with the star Sirius, also known as the Dog Star.The ancient Greeks and Romans referred to the period of time when Sirius, the brightest star in the constellation Canis Major the Greater Dog would appear to rise just before the sun as the dog days. The phrase actually originated from an astronomical event when Sirius would line up with the Sun during late July. The Greeks and Romans believed that the stars brightness added to the suns heat, making the sweltering temperatures associated with this time of year.Over time, with the shift in the earths axis precession of the equinoxes, the term dog days became generalized and its cooling changed to merely mean the hottest period of summer. .
