How are yom kippur and rosh hashanah related?

Answer 1

Rosh Hashanah is the first two days of the month of Tishrei, and is the Jewish New Year. Our traditions state that at that time the world is judged for the coming year (Talmud, Rosh Hashanah 16a); and during services we read the Torah and say prayers which ask for a good year and which declare God's kingship over the world. The shofar (ram's horn) is blown (Leviticus 23:24; Talmud, Rosh Hashanah 33b-34a), symbolically heralding God's kingship, and calling to mind the covenant of Isaac (see Genesis ch.22). Festive meals are held in the home, and traditional foods (such as the well-known apple dipped in honey) are eaten to symbolize a sweet year (See Talmud, Keritut 6a).

On Rosh Hashanah we proclaim God as our King and submit to His judgment. Blessing for the coming year is based on our performance in the previous year and our repentance. On Yom Kippur the decree is sealed. On each Rosh Chodesh (beginning of the month) we are again judged to see if we are still worth to receive the blessing allocated for that month. Each Shabbat the blessing for the following week is brought down.
