Winter Solstice arrives today, which is the 22nd solar term in the traditional Chinese calendar. It is also a traditional Chinese festival, commonly known as Midwinter, the Longest Night. Ancient Chinese had determined the date of the Winter Solstice with the sundial over 2,500 years ago in the Spring and Autumn Period. It comes annually between December 21 and December 23 in Northern Hemisphere according to Gregorian calendar. Today has the shortest daytime and the longest nighttime in the whole year. This holiday is observed across most areas of China, during which northerners usually eat dumplings and southerners have sweet dumplings and pumpkins. Let's eat dumplings together on the arrival of Midwinter, as the saying goes.
