The traditional Chinese solar calendar divides the year into 24 solar terms. Summer Solstice, the 10th solar term of the year, begins on June 21 this year and ends on July 6.

夏至是中國傳統(tǒng)二十四節(jié)氣的第10個節(jié)氣，今年的夏至從6月21日開始，7月6日結(jié)束。

At this time, much of the northern hemisphere receives the most hours of daylight, but it does not bring the hottest temperatures which will come only 20 to 30 days later.

在這一天，北半球的大部分地區(qū)白晝最長，但是氣溫卻不是一年中最高的，最高氣溫將出現(xiàn)在20到30天后。

The following are 6 things you might not know about Summer Solstice.

來看看關于夏至的6個小常識。

The longest day of the year

夏至這天白晝最長

On the Summer Solstice itself, daylight lasts the longest for the whole year in the northern hemisphere. After this day, daylight hours get shorter and shorter and temperatures become higher in the northern hemisphere.

在夏至這天，北半球的白晝是全年最長的。過了夏至，北半球的白晝越來越短，氣溫卻會繼續(xù)升高。

How long is the longest day in China? According to the expert Yan Jiarong, the entire day in Mohe in Heilongjiang province, located in the northernmost tip of China, lasts nearly 17 hours when you include dawn, twilight and its afterglow. Summer Solstice is the best season for viewing the aurora in Mohe, "the sleepless town of China".

中國境內(nèi)的白晝最長能達到幾個小時呢？據(jù)專家嚴家榮介紹，在中國最北端黑龍江省漠河,算上黎明、黃昏和落日余暉，晝長可持續(xù)近17個小時。夏至是在“中國不夜城”漠河觀賞極光的最佳時節(jié)。
