If you are in the Northern Hemisphere, the increase rate of daylight hours depends on your location's latitude-in more northern latitudes you will see a rapid increase in daylight hours compared to if you're in the more southern latitudes. Daylight Hours Increase Faster in the North Why isn't the year's earliest sunset on the winter solstice? 9. This happens because of the difference between how we measure time using watches and the time measured by a sundial. Most places in the Northern Hemisphere see their earliest sunset a few days before the solstice and their latest sunrise a few days after the solstice. In fact, the Earth is on its perihelion-the point on the Earth's orbit closest to the Sun-a few weeks after the December solstice.Įarth: The living planet 8. ![]() Therefore, different amounts of sunlight reach the Northern and Southern Hemispheres, causing variation in temperatures and weather patterns thoughout the year. Seasons occur because Earth orbits the Sun on a slant, with an axial tilt of around 23.4 degrees. Different seasons are not defined by how far the Earth is from the Sun. The Earth Isn't Farthest From the Sunĭuring winter in the Northern Hemisphere, the Earth is actually closest to the Sun. For meteorologists, on the other hand, winter begins three weeks earlier, on December 1. In the Northern Hemisphere, astronomers and scientists use the December solstice as the start of the winter season, which ends on the March equinox. It's the First Day of Astronomical Winter It's also common to call it the day the Sun turns around. The Sun seems to stand still at the Tropic of Capricorn and then reverses its direction. The term solstice comes from the Latin word solstitium, meaning 'the Sun stands still.' This is because on this day, the Sun reaches its southern-most position as seen from the Earth. The last December 23 solstice was in 1903 and will not happen again until 2303. The December solstice can happen on December 20, 21, 22, or 23, though December 20 or 23 solstices are rare. On the June solstice, the Sun is directly overhead the Tropic of Cancer (latitude 23° 30′ North) in the Northern Hemisphere, while on the December solstice, the Sun shines directly over the Tropic of Capricorn (latitude 23° 30′ South) in the Southern Hemisphere. Solstices happen twice a year-once around June 21 and then again around December 21. Business Date to Date (exclude holidays).
