《史记·八书·封禅书》
二年以后，适逢十一月甲子日朔旦为冬至节，推算历法的人认为这一天是进入统岁的开始，所以天子亲自到泰山下，在这一天于明堂祭祀天帝，但不行封禅礼。
其後二岁，十一月甲子朔旦冬至，推历者以本统。天子亲至泰山，以十一月甲子朔旦冬至日祠上帝明堂，毋脩封禅。
Two years later, the first day of the eleventh month, jiazi, coincided with the winter solstice. The astronomers believed that this day marked the beginning of a new year, and hence the Son of Heaven himself went to the foot of Mount Tai to venerate the Lord of Heaven in the Ming Hall on that day, but he did not perform the Feng and Shan rituals.
