Avodah Zarah 8 - The Origin of Calenda and Saturnalia
When Adam, the first man, saw the days decreasing in winter, he said, "Woe is to me! This is the death that has been decreed upon me!" He then engaged in fasting and prayer for eight days. When, after the winter solstice, he saw that the days began increasing, he said, "This is the way of the world!" and established eight days of festivities. The following year he established both eight-day periods as festival days. Although he intended for the sake of Heaven, later generations dedicated them for the sake of idolatry.
