The longest day of the year

夏至这天白昼最长

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.

在夏至这天，北半球的白昼是全年最长的。过了夏至，北半球的白昼越来越短，气温却会继续升高。

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".

中国境内的白昼最长能达到几个小时呢？据专家严家荣介绍，在中国最北端黑龙江省漠河,算上黎明、黄昏和落日余晖，昼长可持续近17个小时。夏至是在“中国不夜城”漠河观赏极光的最佳时节。
