The longest day of the year
The summer solstice
"The summer solstice" is the 10th solar term in the 24 solar terms. It begins when the Sun reaches the celestial longitude of 90° and ends when it reaches the longitude of 105°. It usually happens on June 21 or June 22 and ends on July 7 or July 8.
The summer solstice sun is almost direct to the Tropic of Cancer, the northern hemisphere is the longest day, the Arctic Circle and the area north of the sun are not falling all day, forming the largest area of the largest day. After this day, the sun direct position to move south, the northern hemisphere day is gradually shortened, sunrise, sunset direction also began to move south. In the Tropic of Cancer and its north, noon sun height is also declining, the sun-shadows is gradually being stretched. But because of the solar radiation to the ground energy still more than the ground to the air divergence, so in a short time the temperature continues to rise.
夏至
夏至是24个节气中第10个节气，也是夏季的第4个节气。它开始于当太阳到达90°的天文经度时，到达105°的经度时结束。通常发生在6月21日或6月22日，7月7日或7月8日结束。
夏至日太阳几乎直射北回归线，北半球白昼最长，北极圈及其以北的地区太阳整日不落，形成面积最大的极昼区。此日过后，阳光直射位置向南移动，北半球白昼逐渐减短，日出、日落的方位也开始往南移动。在北回归线及其以北地区，正午太阳高度亦日渐降低，日影逐渐被拉长。但由于太阳辐射到地面的能量仍比地面向空中发散的多，所以在短时间内气温继续升高。
