The Lantern Festival or the Spring Lantern Festival is a Chinese festival celebrated on the fifteenth day of the first month in the lunisolar Chinese calendar. Usually falling in February or early March on the Gregorian calendar, it marks the final day of the traditional Chinese New Year celebrations. As early as the Western Han Dynasty (206 BCE–25 CE), it had become a festival with great significance. During the Lantern Festival, children go out at night carrying paper lanterns and solve riddles on the lanterns ().
