The traditional Chinese solar calendar divides the year into 24 solar terms.
Summer Solstice, or Xiazhi (Chinese: 夏至), the 10th solar term of the year, begins on June 21 this year and ends on July 5.
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.
