Other names of Solstice
Although the winter solstice under different names in different parts of the world, their designation on the basis of monthly income and have hemisphere is known worldwide acceptance. Basically, this astronomical phenomenon – it is because the sun reaches its maximum declination, meets twice a year – once in June, as it is said in the June solstice, then in December, due to which they called December solstice. Although these names are given based on the phenomenon will take place, perhaps outside the hemisphere, where the sun is positioned to be named.

Winter solstice and summer solstice
Summer solstice and the longest day of the year
Initially, the days and nights due to the rotation of the earth, with the side facing the sun knows the day and the night side caused other experiences. Since the earth on its axis is inclined at an angle of 23 ° 26 ‘, at a point which is fixed in a position such that it is inclined either towards or away from the sun. Such an orientation, the apparent position of the sun is perpendicular to the Tropic of Cancer and the Tropic of Capricorn, is called the summer solstice. It happens twice a year (once if the inclination of the Earth’s axis is tilted toward the sun, and once when the slope tilted away from the sun.
This phenomenon and the apparent position of the sun in the sky, the sun extreme north or south, when the tower will determine the duration of a day. When the sun is at the Tropic of Cancer, the northern hemisphere receives more sunlight and therefore have. Longer days and shorter nights if there are on the Tropic of Capricorn, things work the other way, and in the southern hemisphere experiencing daylight for a longer period. In other words, the hemisphere of the planet, the sun is inclined towards more light and thus teaches days here are long and the nights short.
