In which place in prayer are personal requests inserted? What are the different opinions, and what is the basis for the dispute?

What are the holidays of the idol worshippers during which there is a prohibition to sell to or buy from them? The Gemara works on the list of holidays and explains the reason behind the establishment of each of the holidays. Kalenda and Saturnalia were established in response to the first year of the first man (Adam) when he saw in winter that the days were getting shorter and thought that, because of his sin, God was returning the world to chaos. When he saw that the days were getting longer, he realized it was just the way of the world and established a holiday before and after that day on which the days began to lengthen (winter solstice).

Another holiday was established in response to the successes of the Roman kingdom against the Egyptians and the Greeks. Rav Dimi explained that the Jews helped the Romans in their victory over the Greeks and ruled together with the Romans for twenty-six years before the Romans subjugated the Jews.
