After the 12-day Christmas celebration ended on Epiphany, St. Distaff’s Day was traditionally the day on which women resumed their chores, symbolized by the distaff, a tool used in spinning flax or wool. It was also called Rock Day—”rock” being another name for the distaff. The “spear side” and the “distaff side” were legal terms used to distinguish the inheritance of male from that of female children, and the distaff eventually became a synonym for the female sex as a whole. Distaff Day was not really a church festival, but it was widely observed at one time in England. Discuss
