Status as a Jewish holy day
The Tanakh and
siddur describe Shabbat as having three purposes:
# To commemorate
God's creation of the universe, on the seventh day of which God rested from (or ceased) his work;
# To commemorate the Israelites' Exodus and redemption from slavery in
ancient Egypt
Ancient Egypt () was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150BC (according to conventional Egyptian chronology), when Upper and Lower E ...

Judaism accords Shabbat the status of a joyous holy day. In many ways,
Jewish law gives Shabbat the status of being the most important holy day in the

is read during the
Torah reading which is part of the Shabbat morning services, with a longer reading than during the week. The Torah is read over a yearly cycle of 54 ''
parashioth'', one for each Shabbat (sometimes they are doubled). On Shabbat, the reading is divided into seven sections, more than on any other holy day, including
Yom Kippur. Then, the
Haftarah reading from the Hebrew prophets is read.

Jewish Messiah will come if every Jew properly observes two consecutive Shabbatoth.

Rituals
Welcoming Shabbat

Honoring Shabbat (''kavod Shabbat'') on Preparation Day (Friday) includes bathing, having a haircut and cleaning and beautifying the home (with flowers, for example).
Days in the Jewish calendar start at nightfall, therefore many
Jewish holidays begin at
such time. According to Jewish law, Shabbat starts a few minutes before sunset. Candles are lit at this time. It is customary in many communities to light the candles 18 minutes before sundown (''tosefet Shabbat'', although sometimes 36 minutes), and most printed Jewish calendars adhere to this custom.
The
Kabbalat Shabbat service is a prayer service welcoming the arrival of Shabbat. Before Friday night dinner, it is customary to sing two songs, one "greeting" two Shabbat angels into the house (
"''Shalom Aleichem''" -"Peace Be Upon You") and the other praising the woman of the house for all the work she has done over the past week (
"''Eshet Ḥayil''" -"Woman Of Valour"). After blessings over the wine and
challah, a festive meal is served. Singing is traditional at Sabbath meals. In modern times, many composers have written sacred music for use during the Kabbalat Shabbat observance, including
Robert Strassburg and
Samuel Adler.
According to
rabbinic literature
Rabbinic literature, in its broadest sense, is the entire corpus of works authored by rabbis throughout Jewish history. The term typically refers to literature from the Talmudic era (70–640 CE), as opposed to medieval and modern rabbinic ...
, God via the Torah commands Jews to ''observe'' (refrain from forbidden activity) and ''remember'' (with words, thoughts, and actions) Shabbat, and these two actions are symbolized by the customary two
Shabbat candles. Candles are lit usually by the woman of the house (or else by a man who lives alone). Some families light more candles, sometimes in accordance with the number of children.
Other rituals
Shabbat is a day of celebration as well as
prayer

. It is customary to eat three festive meals: Dinner on Shabbat eve (Friday night), lunch on Shabbat day (Saturday), and a third meal (a ''
Seudah shlishit'') in the late afternoon (Saturday). It is also customary to wear nice clothing (different from during the week) on Shabbat to honor the day.
Many Jews attend synagogue services on Shabbat even if they do not do so during the week. Services are held on Shabbat eve (Friday night), Shabbat morning (Saturday morning), and late Shabbat afternoon (Saturday afternoon).
With the exception of
Yom Kippur, days of public fasting are postponed or advanced if they coincide with Shabbat. Mourners sitting ''
shivah'' (week of mourning subsequent to the death of a spouse or first-degree relative) outwardly conduct themselves normally for the duration of the day and are forbidden to display public signs of mourning.
Although most Shabbat laws are restrictive, the fourth of the Ten Commandments in Exodus is taken by the Talmud and

to allude to the ''positive'' commandments of Shabbat. These include:
* Honoring Shabbat (''kavod Shabbat''): on Shabbat, wearing festive clothing and refraining from unpleasant conversation. It is customary to avoid talking on Shabbat about money, business matters, or secular things that one might discuss during the week.
* Recitation of ''kiddush'' over a cup of
wine

at the beginning of Shabbat meals, or at a reception after the conclusion of morning prayers (see the
list of Jewish prayers and blessings).
*

Eating three festive meals. Meals begin with a blessing over two loaves of bread (
lechem mishneh', "double bread"), usually of braided challah, which is symbolic of the double portion of
manna that fell for the Jewish people on the day before Sabbath during their 40 years in the desert after the Exodus from Ancient Egypt. It is customary to serve meat or fish, and sometimes both, for Shabbat evening and morning meals. ''
Seudah Shlishit'' (literally, "third meal"), generally a light meal that may be
pareve or
dairy, is eaten late Shabbat afternoon.
* Enjoying Shabbat (''oneg Shabbat''): Engaging in pleasurable activities such as eating, singing, sleeping, spending time with the family, and marital relations. Sometimes referred to as "Shabbating".
* Recitation of ''
havdalah''.
Ending Shabbat

''Havdalah'' (Hebrew: הַבְדָּלָה, "separation") is a Jewish religious ceremony that marks the symbolic end of Shabbat, and ushers in the new week. At the conclusion of Shabbat at nightfall, after the appearance of three stars in the sky, the ''havdalah'' blessings are recited over a cup of wine, and with the use of fragrant spices and a candle, usually braided. Some communities delay ''havdalah'' later into the night in order to prolong Shabbat. There are different customs regarding how much time one should wait after the stars have surfaced until the sabbath technically ends. Some people hold by 72 minutes later and other hold longer and shorter than that.
Prohibited activities
Jewish law (halakha) prohibits doing any form of ''melakhah'' (מְלָאכָה, plural ''melakhoth'') on Shabbat, unless an urgent human or medical need is life-threatening. Though ''melakhah'' is commonly translated as "work" in
English, a better definition is "deliberate activity" or "skill and craftmanship". There are 39 categories of ''melakhah'':
* plowing earth
* sowing
* reaping
* binding sheaves
* threshing
* winnowing
* selecting
* grinding
* sifting
* kneading
* baking
* shearing wool
* washing wool
* beating wool
* dyeing wool
* spinning
* weaving
* making two loops
* weaving two threads
* separating two threads
* tying
* untying
* sewing stitches
* tearing
* trapping
* slaughtering
* flaying
* tanning
* scraping hide
* marking hide
* cutting hide to shape
* writing two or more letters
* erasing two or more letters
* building
* demolishing
* extinguishing a fire
* kindling a fire
* putting the finishing touch on an object, and
* transporting an object (between private and public domains, or over 4
cubits within public domain)
The 39 ''melakhoth'' are not so much activities as "categories of activity". For example, while "winnowing" usually refers exclusively to the separation of
chaff from
grain
A grain is a small, hard, dry fruit (caryopsis) – with or without an attached husk, hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and ...
, and "selecting" refers exclusively to the separation of debris from grain, they refer in the Talmudic sense to any separation of intermixed materials which renders edible that which was inedible. Thus, filtering undrinkable water to make it drinkable falls under this category, as does picking small bones from fish (
gefilte fish is one solution to this problem).
The categories of labors prohibited on Shabbat are
exegetically derived – on account of Biblical passages juxtaposing Shabbat observance () to making the
Tabernacle
According to the Hebrew Bible, the tabernacle (), also known as the Tent of the Congregation (, also Tent of Meeting), was the portable earthly dwelling of God used by the Israelites from the Exodus until the conquest of Canaan. Moses was instru ...

. They are not explicitly listed in the Torah; the Mishnah observes that "the laws of Shabbat ... are like mountains hanging by a hair, for they are little Scripture but many laws". Many
rabbinic scholars have pointed out that these labors have in common activity that is "creative", or that exercises control or dominion over one's
environment.
In addition to the 39 ''melakhot'', additional activities were
prohibited by the rabbis for various reasons.
The term ''
shomer Shabbat'' is used for a person (or organization) who adheres to Shabbat laws consistently. The (strict) observance of the Sabbath is often seen as a benchmark for orthodoxy and indeed has legal bearing on the way a Jew is seen by an
orthodox religious court regarding their affiliation to Judaism.

devices on or off is prohibited as a ''melakhah''; however, authorities are not in agreement about exactly which one(s). One view is that tiny sparks are created in a switch when the circuit is closed, and this would constitute lighting a fire (category 37). If the appliance is purposed for light or heat (such as an
incandescent bulb or electric oven), then the lighting or heating elements may be considered as a type of fire that falls under both lighting a fire (category 37) and cooking (i.e., baking, category 11). Turning lights off would be extinguishing a fire (category 36). Another view is that completing an electrical circuit constitutes building (category 35) and turning off the circuit would be demolishing (category 34). Some schools of thought consider the use of electricity to be forbidden only by
rabbinic injunction, rather than a ''melakhah''.
A common solution to the problem of electricity involves preset timers (
Shabbat clocks) for electric appliances, to turn them on and off automatically, with no human intervention on Shabbat itself. Some Conservative authorities reject altogether the arguments for prohibiting the use of electricity. Some Orthodox also hire a "
Shabbos goy", a non-Jew (who must not be regularly employed by the household in question) to perform prohibited tasks (like operating light switches) on Shabbat.
Automobiles
Orthodox and many Conservative authorities completely prohibit the use of automobiles on Shabbat as a violation of multiple categories, including lighting a fire, extinguishing a fire, and transferring between domains (category 39). However, the Conservative movement's
Committee on Jewish Law and Standards permits driving to a synagogue on Shabbat, as an emergency measure, on the grounds that if Jews lost contact with synagogue life, they would become lost to the Jewish people.

Modifications
Seemingly "forbidden" acts may be performed by modifying technology such that no law is actually violated. In
Sabbath mode, a "
Sabbath elevator" will stop automatically at every floor, allowing people to step on and off without anyone having to press any buttons, which would normally be needed to work. (

Permissions
If a human life is in danger (pikuach nefesh), then a Jew is not only allowed, but required, to violate any halakhic law that stands in the way of saving that person (excluding murder, idolatry, and forbidden sexual acts). The concept of life being in danger is interpreted broadly: for example, it is mandated that one violate Shabbat to bring a woman in active labor to a hospital. Lesser rabbinic restrictions are often violated under much less urgent circumstances (a patient who is ill but not critically so).
Various other legal principles closely delineate which activities constitute
desecration of Shabbat. Examples of these include the principle of ''shinui'' ("change" or "deviation"): A violation is not regarded as severe if the prohibited act was performed in a way that would be considered abnormal on a weekday. Examples include writing with one's nondominant hand, according to many rabbinic authorities. This legal principle operates ''bedi'avad'' (''
ex post facto'') and does not cause a forbidden activity to be permitted barring extenuating circumstances.
Reform and Reconstructionist views
Generally, adherents of
Reform and
Reconstructionist Judaism believe that the individual Jew determines whether to follow Shabbat prohibitions or not. For example, some Jews might find activities, such as writing or cooking for
leisure
Leisure (, ) has often been defined as a quality of experience or as free time. Free time is time spent away from business, Employment, work, job hunting, Housekeeping, domestic chores, and education, as well as necessary activities such as ...
, to be enjoyable enhancements to Shabbat and its holiness, and therefore may encourage such practices. Many Reform Jews believe that what constitutes "work" is different for each person, and that only what the person considers "work" is forbidden. The radical Reform rabbi
Samuel Holdheim advocated moving Sabbath to Sunday for many no longer observed it, a step taken by dozens of congregations in the United States in late 19th century.
More rabbinically traditional Reform and Reconstructionist Jews believe that these ''halakhoth'' in general may be valid, but that it is up to each individual to decide how and when to apply them. A small fraction of Jews in the Progressive Jewish community accept these laws in much the same way as Orthodox Jews.
Encouraged activities
The Talmud, especially in tractate Shabbat, defines rituals and activities to both "remember" and "keep" the Sabbath holy and to sanctify it at home and in the synagogue. In addition to refraining from creative work, the sanctification of the day through
blessings over wine, the preparation of special
Sabbath meals, and engaging in
prayer

and
Torah study were required as an active part of Shabbat observance to promote intellectual activity and spiritual regeneration on the day of rest from physical creation. According to many scribes, half of the day should be devoted to Torah study and prayer. The Talmud states that the best food should be prepared for the Sabbath, for "one who delights in the Sabbath is granted their heart's desires" (
BT, Shabbat 118a-b).
All
Jewish denominations encourage the following activities on Shabbat:
