The length of the shortest day of the year depends on the location. In the United States, some areas get less than 4 hours of sunshine on the shortest day. In places like Washington and New York, the shortest day lasts for up to 9 1/2 hours.Know More
The shortest day of the year falls on the winter solstice. In the Northern Hemisphere, this is usually between December 20 and December 23. In the Southern Hemisphere, the shortest day is between June 20 and June 22. The December solstice occurs when the North Pole is at its furthest tilt away from the sun.
How much sunlight there is on the shortest day depends on the location and does not necessarily mean the latest sunrise or the earliest sunset. The earliest sunsets usually occur about 2 weeks before the winter solstice and the latest sunrise about 2 weeks afterward. In parts of the Arctic, there is no daylight at all. Variation in the length of sunlight also occurs across the U.S.:
The summer solstice is the longest day of the year because the Earth's tilt is greatest toward the Sun on that day. The axis of the Earth is tilted 23.5 degrees from the vertical as it follows its orbital path. This means that for part of the year, the Northern Hemisphere is tilted closer to the Sun, giving that half of the planet more daylight per revolution.Full Answer >
The hot weather that occurs in summer is caused by the Earth's axial tilt, which affects how much sunlight different parts of the Earth experience throughout the year. During summer in the northern hemisphere, that half of the globe is tilted 23.5 degrees toward the sun, increasing both the length of the day and the amount of time the sun has to warm the surface.Full Answer >
May is the fifth month of the year. There are 31 days and three notable holidays that are observed during the month: Cinco de Mayo, Mother's Day and Memorial Day.Full Answer >
The change in seasons is caused by the varying angle of the Earth's tilt from one part of the year to another. A common misconception is that the change in seasons is due to the Earth's slightly elliptical orbit bringing the planet closer to the sun in summer, but, as About.com notes, seasons are different in the northern hemisphere and the southern, which are the same distance from the sun.Full Answer >
