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

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.

In China, the 24 solar terms were created thousands of years ago to guide agricultural production. But the solar term culture is still useful today to guide people's lives through eating special foods, performing cultural ceremonies and even healthy living tips that correspond with each solar term.
