"Dog Days" refers to the hottest period of summer, typically occurring in July and August in the Northern Hemisphere. The term originates from ancient Greece and Rome, where it was associated with the rising of the star Sirius, also known as the Dog Star, which is part of the Canis Major constellation. This time was believed to bring heat, drought, and discomfort. In modern usage, "Dog Days" can also describe a sluggish or lazy time, often when people and animals feel lethargic due to the heat. Many cultures celebrate this season with various traditions, enjoying outdoor activities and summer festivities while trying to stay cool.
