Why The Shortest Day Of The Year Isn't The Coldest

The video explores the concept of seasons, explaining that while we often think of summer and winter as opposites due to temperature, seasons are technically defined by daylight patterns. The astronomical system uses equinoxes and solstices to mark seasons, with daylight oscillating in a sine wave pattern. This results in summer being spring in reverse, and winter being fall in reverse. However, temperature changes lag behind daylight changes, explaining why summer is hotter despite having similar daylight to spring. Daylight's consistency over temperature has historically made it a reliable marker for seasons.
