A new mishnah! Listing the non-Jewish holidays, by name. Plus, other more local celebrations, based on the locale or a given family's rejoicing. Also, the story of Adam's first year, when the days were increasing in dark before the winter solstice, and his fear that it was a punishment - until the days started getting longer again. Also, with regard to Rome - and an allegiance with Israel for 26 years. Plus, the laws of penalties and R. Yehudah ben Bava's success in keeping those halakhot alive during the Hadrianic persecutions.
