In the early 1970s, new rituals began popularizing. Jewish women staged public ceremonies for the birth of their daughters, sharing the ritual of "brit millah" which was historically reserved for newborn sons. They started forming special groups for prayer and study on Rosh Hodesh, the beginning of the new month, with their newfound freedoms to congregate. Women also contributed to the observance of Passover by placing a goblet of water, called "Miriam's cup", on the Seder table to include her, as Moses' sister, in the narrative of his exodus from Egypt with the Jewish people.
