Kaparot
In the early morning hours of the day preceding Yom Kippur, the Kaparot ("Atonement") ceremony is performed. We take a live chicken (a rooster for a male and a hen for a female) and, circling it three times above our heads, we declare: "This is my replacement, this is my exchange, this is my atonement; this fowl shall go to its death, and I shall go to a long, good and peaceful life." The fowl is then slaughtered in accordance with halachic procedure, at which time we contemplate that this is a fate we ourselves would deserve, G-d forbid, for our failings and iniquities. The value of the fowl is given to the poor, and its meat eaten in the Yom Kippur meal; some give the fowl itself to the poor. (A alternate custom is to perform the rite only with money, reciting the prescribed verses and giving the money to charity. Kaparot can also be performed in the preceding days, during the "Ten Days of Repentance").

Omit Tachnun
Tachnun (confession of sins) and similar prayers are omitted.
Festive Meals
The day before Yom Kippur is a Yom Tov, a festive day; for although we stand prepared to be judged in the supernal courtroom for our deeds of the passed year, we are confident that G-d is a merciful judge, and will decree a year of life, health and prosperity for us. Two festive meals are eaten -- one at midday and the other before the fast, which begins at sunset. The Talmud states that "Whoever eats and drinks on the 9th [of Tishrei], it is regarded as if he had fasted on both the 9th and the 10th."
In many communities it is customary to eat kreplach on the day before Yom Kippur. Kreplach are small squares of rolled pasta dough filled with ground meat and folded into triangles. They can be boiled and served in soup or fried and served as a side dish. The meat symbolizes severity, the dough is an allusion to kindness. In preparation for the Day of Judgment we "cover" the severity with kindness. (Click here for a recipe.)

Mikveh
Both men and women immerse in a mikveh (ritual pool) to attain an extra measure of sanctity before the holy day.
Lekach (honey cake)
It is customary to ask for and receive lekach (sweet cake -- signifying a sweet year) from someone (usually one's mentor or parent) on this day. One of the reasons given for this custom is that if it had been decreed, G-d forbid, that during the year we should need to resort to a handout from others, the decree should be satisfied with this asking for food. The Lubavitcher Rebbe adds a deeper insight: "asking for lekach" on the eve of Yom Kippur instills in us the recognition that all the sustenance we receive throughout the year, including that which we supposedly "earn" by our own powers and endeavors, is in truth a gift from Above, granted in response to our daily requests from "He who nourishes the entire world with in His goodness, with grace, with benevolence and with compassion."

Additional customs
Additional eve of Yom Kippur customs include receiving symbolic malkut ("lashings") as atonment for one's transgressions, reciting the "Al Chet" confession of sins after minchah and at sunset, and lighting a 26-hour candle that would burn for the duration of Yom Kippur.
Yom Kippur fast begins before sunset
Yom Kippur ("Day of Atonement"), the holiest day of the year, begins this evening before sunset. Its most basic observance is the fast that begins this evening and ends tomorrow evening at nightfall (a total of approximately 26 hours), during which we abstain from food and drink in fulfillment of the biblical command (Leviticus 16:29; see also "Festive Meals" above).
For more on the Yom Kippur observances see Laws & Customs for tomorrow, Tishrei 10.
Kol Nidrei
The first of the five Yom Kippur prayer services, which begins with the solemn Kol Nidrei prayer, is recited in the synogogue tonight at sunset, at the onset of the holy day.

Yom Kippur is the holiest day of the year -- the day on which we are closest to G-d and to the quintessential core of our own souls. It is the "Day of Atonement" -- "For on this day He will forgive you, to purify you, that you be cleansed from all your sins before G-d" (Leviticus 16:30).
For twenty-six hours, from several minutes before sunset on Tishrei 9 to after nightfall on Tishrei 10, we "afflict our souls": we abstain from food and drink, do not wash or anoint our bodies, do not wear leather shoes, and abstain from marital relations.
When the Holy Temple stood in Jerusalem, the Yom Kippur service included the High Priest's entry into the "Holy of Holies" to offer the ketoret -- the only time that anyone entered the Temple's innermost chamber -- and the "casting of lots" over two goats, one to be offered to G-d and the other to carry off the sins of Israel to the wilderness. Today, we spend the day in the synagogue garbed in a white garment called a kittel to resemble the sin-free angels and to waken thoughts of repentance by reminding us of the day of our death. In the course of the day we hold five prayer services: Maariv, with its solemn Kol Nidrei service, on the eve of Yom Kippur; Shacharit; Musaf, which includes a detailed account of the Temple service; Minchah, which includes the reading of the Book of Jonah; and Ne'illah, the "closing of the gates" service at sunset. We say the Al Chet confession of sins ten times, and recite Psalms every available moment.
The day is the most solemn of the year, yet an undertone of joy suffuses it: a joy that revels in the spirituality of the day and expresses the confidence that G-d will accept our repentance, forgive our sins, and seal our verdict for a year of life, health and happiness. When the closing Ne'illah service climaxes in the resounding cries of "Hear O Israel... G-d is one" and a single blast of the shofar, the joy erupts in song and dance (a Chabad custom is to sing the lively niggun known as "Napoleon's March"), followed by the festive after-fast meal, making the evening following Yom Kippur a Yom Tov (festival) in its own right.
