Shabbat dinner on Friday Evening is usually the most elaborate meal of the week. Observant Jews will light shabbat candles at home just before sunset, and begin the meal with kiddush, a special prayer and blessing over wine and bread. The bread is frequently challah, specially baked for Shabbat. If there is not a communal Shabbat kiddush luncheon in the synagogue, Shabbat lunch at home may be more ornate than the usual lunch, either with cold leftovers from dinner, or special dishes like cholent that are slow cooked overnight. At the end of Shabbat, there is a special prayer and ritual called Havdallah that divides Shabbat from the mundane days of the week. All of the Shabbat religious services can be held in the home for Jews who do not go to the synagogue for communal services.
The spice box is not actually passed around until the very end of Shabbat. It is passed around toward the end of the concluding service of Shabbat, called Havdalah. One tradition explains that on Shabbat, each person is given an extra soul. The passing of the spice box at the end of Shabbat makes the loss of this extra soul a little less painful.
If a public fast falls on Shabbat, the fast is delayed until Shabbat is over. The one exception is Yom Kippur. If a public fast falls on Shabbat, you fast the entire day until the end of the fast, even though it means entering Shabbat while fasting.
Whether or not it's celebrated, observed, or even acknowledged, the Shabbat is the seventh day, which, in Judaism, corresponds to Saturday. As in many other ancient cultures, each day in Judaism is considered to begin at sundown and end at the following sundown. Accordingly, the Shabbat begins at sundown on Friday evening and extends until sundown on Saturday evening. Those who observe it, whether in the synagogue, in their homes, or in some part of their private lives, observe it during that period of time.
Shabbat ends of its own accord at the time a bit after sunset on Saturday night. Nothing that mankind does can either extend it or cause it to end. Those who observe the Shabbat can only mark its beginning and its end as they occur. The brief ceremony and set of blessings that mark the very end of shabbat are known as "HAHV-da-LAH", meaning "division" or "boundary" in Hebrew. It marks the boundary between holy and weekday-like. The moment is considered to be a let-down.
