"Rosh Hashanah really stands out in the Jewish calendar as a uniquely, not exclusively, Jewish holiday," said Rabbi Menachem Creditor, scholar-in-residence at the UJA-Federation of New York. "This is a moment where Jews and non-Jews can really come together," he told InsideEdition.com. "It's an invitation to come together as a community way beyond any one of our tribes." The two-day holiday marks the beginning of the Jewish High Holy Days. It's followed by Yom Kippur ten days later.
