Depending on where you live, the last full day of winter, 2012 will be either March 19, March 20, September 22 or September 23. Winter ends at the moment of the earth's orbit when the hemisphere that you are in goes from being tilted away from the sun to being tilted toward the sun. The sun will be directly of the equator at 5:14 AM UTC on March 20. Until that time, the sun will be over the southern hemisphere, and after that time it will be over the northern hemisphere. The sun will be directly over the equator again at 2:29 PM UTC on September 22, after which it will again be over the southern hemisphere.
More direct rays and longer days (summer).
When the southern hemisphere is tilted towards the sun, it is summer below the equator and winter above. Likewise, when the northern hemisphere is tilted towards the sun, it is summer in the north and winter in the south. Hope that helps. Martyn.
Even though the North Pole is tilted toward the sun, it is not tilted all the way (to 90 degrees). The sun still remains low in the sky, and so the pole doesn't experience the full heat of the sun directly overhead. The tilt of the pole is about 23.5 degrees. It is also very cold because the sun doesn't hit the North Pole directly so it is very cold.
The hemisphere tilted toward the Sun experiences longer days (late spring, summer, early fall). The hemisphere tilted away from the Sun experiences shorter days (late fall, winter, early spring). At the equinoxes, around September 23 and March 20, both hemispheres experience about the same amount of daylight.
neither end of Earth's axis is tilted toward the sun.
neither end of Earth's axis is tilted toward the sun.
The 'equinoxes' occur in March and September. At those times, neither pole is tilted toward or away from the sun. At the time of the June solstice, the north pole reaches its maximum tilt toward the sun, whereas at the time of the December solstice, the south pole is at its maximum tilt toward the sun.
Beginning around September 22 and ending on March 21.
From March 21 until September 21, maximum on June 21.
It is at that time, when the southern hemisphere is tilted toward the sun, that the northern hemisphere is tilted away from the sun.
This will happen in spring and autumn on days known as the equinoxes - roughly March 21 and September 22IN ADDITION:In the spring equinox on march 21 the earth tilts away from the sun. On September 23 the autumnal equinox, it tilts towards the sun. We are actually closer to the sun in the wintertime in the northern hemisphere.
During the portion that the Earth traverses during the periodfrom roughly March 21 until roughly September 22.
Beginning around September 22 and ending on March 21.
September, 1846 was when Taylor advanced toward Monterrey.

occurs twice per year, sun is direct at the equator and neither hemisphere is pointed toward or away from the sun....... ( around March 21 and around September 23) * means EQUAL Day and Night* Spring and Fall*
