The holiest day of the Jewish year and the culmination of a season of self-reflection. Jews fast, abstain from other worldly pleasures, and gather in prayers that last throughout the day. Following Ne’ilah, the final prayers, during which Jews envision the Gates of Repentance closing, the shofar is sounded in one long blast to conclude the holy day. It is customary to begin building one’s sukkah as soon as the day ends.
