To fulfill kiddush requirements of “establishing a meal,” you need not drink the wine or grape juice (but someone must drink it).  Instead, you may hear kiddush and then simply eat the required amount of bread or mezonot (see above).  This applies to Shabbat or Jewish festivals, evening or morning.

Owning a business that has any violations of Torah laws is forbidden.

Tachanun is related to judgment. Tachanun is NOT said at times of din/judgment:

• At night,
• On Tish'a B'Av,
• In a house of mourning, and
• Yom Kippur.

Tachanun is also NOT said at times of simcha/happiness:

• Shabbat,
• Jewish festivals,
• Rosh Hashana, and
• Rosh Chodesh.

• Isru chag (the day after each of the Jewish festivals),
• Entire month of Nisan.

• All of Chanuka, Purim, Shushan Purim, Tu B'Shvat, Rosh Chodesh, and from Rosh Chodesh Sivan until the day after Shavuot.
• Tishrei from shacharit before Yom Kippur until after Simchat Torah (Shmini Atzeret in Eretz Yisrael). Resume saying tachanun:
  • Second day of Cheshvan, or
  • Day after isru chag of Simchat Torah (this is the more prevalent custom among Ashkenazim). Each person should follow his or her family or community custom.

• Mohel,
• Sandak, or
• Father of a boy having his circumcision.

It is a non-binding custom to braid challa as a reminder of the 12 showbreads (lechem ha'panim) in the Temple that were changed each Shabbat. Proper practice is to braid each challa from six pieces of dough, as there were two columns of six loaves each.
Note Since these showbreads were not changed on Rosh Hashana and Jewish festivals, we may use round challot for those holidays (unless they fall on Shabbat or the holiday is Passover!).

The dead person benefits if his/her son or sons lead public prayer services, whether during shloshim or the entire year (11 or 12 months). However, if the mourner is uncomfortable leading the minyan or is not a good reader or will be embarrassed, he should not feel obligated to do so.

 

A mourner does not lead a minyan on:

• Shabbat;

• Jewish Festivals (including chol ha'moed);

• Purim;

• Rosh Chodesh.

Opinions differ concerning Chanuka, so follow your local custom.

Begin saying L'David Adonai ori v'yish'i (Psalm 27) on the first day (at night) of Elul, not the first day of Rosh Chodesh Elul (the 30th of Av). The last day to say this Psalm is 22nd of Tishrei (Shmini Atzeret). This Psalm is recited twice daily, in shacharit after shir shel yom and in ma'ariv after alenu, including on Shabbat and Jewish festivals.

It is a custom for fathers to cover their sons' heads with their talit while the priests/cohanim bless the congregation.

You must separate a small portion of dough for the cohanim/priests whenever you make bread, rolls, or pizza of the Five Grains in certain quantities. This separated portion is called “challa.”
Note Since there is no Temple at present, we burn the portion of dough.
The requirement to separate challa applies to dough baked at home or commercially (such as a pizza shop), whether for eating on weekdays or for Shabbat/Jewish festivals. For more details, see Challa.
 

You must tear four vertical inches at the neck of your shirt (and jacket, too, if you wear one) when seeing the ruins of the Temple in Jerusalem for the first time in more than 30 days. You do not need to be close by; do kri'a even if you see the mosques that are on top of the Temple mount.

The minimum amount of prayer that women and girls 12 years old and up must say varies according to several opinions:

• Opinion that RMH approves of:
  • Birchot ha'shachar (from al netilat yadaim--to u'maflee la'asot)
  • Birchot haTorah (from la'asok b'divrei Torah--to notein haTorah)
  • Yevarechecha/Eilu divarim she'ein/Eilu divarim she'adam
  • Elohai neshama
  • Asher natan 'sechvi... gomel chasadim tovim l'amo Yisrael
  • Shema (first line of shema plus Baruch shem kevod malchuto l'olam va'ed)
  • If they choose to say the morning amida, they should precede it with emet, v'yatziv until ga'al yisrael.
• Ramban: Women should say at least the amida of shacharit and of mincha.
• Another opinion: Women must say some prayer every day (but it may be any type of prayer, not only the fixed prayer services).
• Another opinion: Women do not need to say the amida and emet v'yatziv on Shabbat and Jewish festivals (that is, whenever we are not asking for anything). 
• Women who have small children who require the mother's constant attention should not say any prayers except for birchot ha'shachar and birchot haTorah.

For more on women and the shema, see Women and Shema in Shacharit.

Shabbat was the goal of Creation. Just as God completed the world's creation on the sixth day and ceased His work on the seventh, so Jews are supposed to imitate God and not do any creative work on the seventh day. Everything we need for living through Shabbat must be prepared ahead so that we do not do any creative activities on Shabbat.
Our observance of Shabbat thus testifies that God created the world. In the Shabbat kiddush, we mention the Exodus from Egypt, too, to testify to the world that God is continuously involved in our lives.
By ceasing our normal efforts to dominate the physical world, we can appreciate the spiritual aspects of our existence.
On Shabbat, all observant (shomer Shabbat) Jews receive an extra “soul.”

Zachor and Shamor

Remember (Zachor) the Sabbath day to make it holy—Exodus/Shmot 20:8
Observe (Shamor) the Sabbath day to make it holy—Deuteronomy/Devarim 5:12
Shabbat has two dimensions:

• Zachor  “Remember,” encompassing positive (“to do”) commandments, and
• Shamor  “Observe,” encompassing negative (“refrain from”) commandments.

Zachor:  Positive Shabbat Commandments
What Are Positive Shabbat Commandments
Positive Shabbat commandments include:

• Lighting candles,
• Making kiddush evening and morning,
• Making havdala,
• Honoring Shabbat (Kivod Shabbat), and
• Enjoying Shabbat (Oneg Shabbat), including eating three meals on Shabbat.

Honoring Shabbat: Special Food and Clothes
Honoring Shabbat includes eating tasty food and wearing nice clothes.

Shamor: Negative Shabbat Commandments
Shabbat Laws from the Torah (Shabbat D'Oraita)
What Are Melachot
On the Jewish day of rest, we refrain from 39 creative activities (melachot) that had been used to build the Tabernacle in the wilderness. These 39 melachot, prohibited by the Torah, are listed in the mishna of Shabbat and in later halacha books.

The word melacha is frequently mistranslated as “work,” but work has nothing to do with the Jewish concept of melacha. Some melachot are physically strenuous (plowing, grinding wheat, skinning an animal) and some are easy to do (drawing, baking). The defining point is whether the activity is one of the 39 creative, value-adding labors. Emptying your pockets before leaving an eruv (so you are not “carrying”) may seem confusing to someone who thinks that resting on Shabbat means refraining only from hard physical labor!

What Are Toldot
Toldot are variations of the 39 melachot. These types of melacha are also prohibited by the Torah.

Intention and Other Considerations
Most Torah (d'oraita) prohibitions of melacha on Shabbat are for cases in which you:
            1) Intend a permanent change.
                Often, actions that may be forbidden when they cause permanent change, will
                be permissible by Torah law if the result is only temporary. Or
            2) Intend or act for a specific purpose.
                Random or unintended actions are generally not prohibited by Torah law.
                (However, actions that are not prohibited by the Torah, may be prohibited
                by Chazal.)

Whether you may benefit from a melacha done on Shabbat depends on intention:

• A Jew who intentionally does a melacha on Shabbat may never benefit from that melacha.

            Note Any other Jew may benefit from that melacha as soon as Shabbat is over.

• A Jew who does melacha on Shabbat by mistake (shogeg) may benefit from that melacha immediately after Shabbat ends.

In order to violate a prohibited melacha d'oraita, the melacha must be done as follows. If any of these do not apply, then the melacha is forbidden d'rabanan but not d'oraita:

• K'darko--The action must be done in a normal way.
• Tzorech tikun—The action must be done for a constructive purpose.
• Tzricha l'gufa--You must need the normal result of that action.
• Asiya b'yachid—The action must be done by one individual (if commonly done by just one person).
• Mit'aseik--You must realize that you are doing a melacha.

 
Shabbat Laws from Chazal (Shabbat D'Rabanan)
Chazal instituted additional restrictions, such as:

• Activities that might lead directly to violating a Torah prohibition.
• Use of items not designated for Shabbat use (muktza). For a good explanation of muktza from the TorahTots website, please click here.
• Activities that might lead one to think that a prohibited activity is permissible (mar'it ayin--the appearance of the eye).
• Activities that are not appropriate for Shabbat, even though they are technically permissible according to the Torah (“uvda d'chol”).
• Tircha--Exerting a physical effort to accomplish a result that is not required for Shabbat.

Enjoying Shabbat/Oneg Shabbat
Chazal instituted laws to engender a positive Shabbat atmosphere and experience.  Beyond the actual halachot of shamor and zachor, we have a concept of enjoying Shabbat (oneg Shabbat)—of enhancing our experience of Shabbat by doing whatever each person finds to be enjoyable and relaxing--as long as it is neither destructive nor violates the laws of Shabbat. The criteria are subjective. To fulfill the idea of honoring Shabbat, do things you would not do just for yourself if it were not Shabbat. Take essential life activities such as eating and sleeping and do them more and better and make them especially enjoyable.

Meals as Oneg
On Shabbat, we eat better foods and more types of food than we would normally do on weekdays.
The main idea behind meals for Shabbat is enjoyment (oneg; by contrast, the main idea for Jewish festivals is joy--simcha), so on Shabbat you should eat bread and either fish, poultry, or meat (but only if you enjoy them).
In order to have a special appetite for our Shabbat evening meal, we don't eat a full meal with bread on Friday afternoon.

Special Shabbat Songs (Zmirot)
Special songs (zmirot) are sung at the various Shabbat meals. Some zmirot have an aspect of prayer to them.

Studying Torah
Studying Torah on Shabbat is another way of increasing our spiritual experience. It honors the Shabbat and should bring about enjoyment of Shabbat.

Shabbat and Muktza
For information on Shabbat and muktza, see section below, Shabbat: Muktza.

Weekday Talk
Don't talk about subjects that are forbidden to do on Shabbat (weekday subjects); for example, don't talk about what you will do after Shabbat is over. There is no prohibition about discussing actions from the past as long as no planning is discussed.

Selecting Good from Bad and Bad from Good
Boreir Principle #1: You may eat anything in the manner in which it is normally eaten.
ExamplePeeling an orange.
 
Boreir Principle #2: You may not use a specialized tool.
 
Boreir Principle #3: You may not remove “bad” from “good.”
What To Do  Take good (edible or desired food) from the undesired (bad) components.
Note You may do this only when you are ready to eat it or when you are preparing the food to be eaten soon afterward.
 
Note Boreir is a complicated area of halacha. Because issues of boreir are almost always from the Torah (d'oraita, not d'rabanan), we are stringent in applying restrictions concerning boreir. Consult a rabbi for specific questions.
 
Selecting Undesired from Desired Food
On Shabbat, you may not usually separate totally undesired from totally desired food in a standard way, even without a specialized tool.
    NOTE As on Jewish festivals, an action needed to eat a food normally (derech achila) does not violate the prohibition of boreir on Shabbat. So you may peel a food that is normally separated from its peel or shell in order to be eaten, as long as you do not use a specialized instrument to do so. For example, on Shabbat, you may do the following by hand without a shinu'i:

• Peel an orange
• Remove the shell of a hard-boiled egg
• Separate peanuts from their shells.

NOTE If peanut shells are then put into a container that also has unshelled peanuts, you may not remove the empty shells from that mixture!
SITUATION You want remove dirt from a carrot's surface on a Shabbat.
WHAT TO DO You may remove the dirt with an altered method (shinu'i), such as scraping the peel with a knife (which is a tool not specialized for separating food)-- but not by using a peeler.
REASON The normal way to eat the carrot is to peel it.
 Selecting Desired from Undesired Food
 
While eating food (and some time before--within the amount of time you would normally need to prepare a meal), you may select desired food from undesired (or inedible) substances by hand or non-specialized tool. You may not use a specialized implement.
EXAMPLE You may remove fish from its skeleton even before eating it, but you may not remove the skeleton from the fish (because you have removed bad from good).
NOTE Once Shabbat has begun:

• You may remove fish bones from fish while you are eating the fish, but not before you are eating the fish.
• You may cut open a melon such as a cantaloupe and shake the seeds out (this is because some of the seeds remain), or take a bite of the melon and spit out the seeds. But you may not remove any remaining seeds using your hand or an implement.

EXCEPTION If you take undesired elements along with the desired food, it is not considered to be separating:  you may use a specialized tool and it does not have to be eaten soon (within the normal food-preparation time).

Shavuot (Yom HaBikurim in the Torah) celebrates and commemorates the giving of the Ten Commandments to the Israelites at Mt. Sinai.
Beginning with the second night of Passover, the Israelites who left Egypt underwent 49 days of spiritual improvement and purification until they were ready to receive the Torah from God (Shavuot ends this 49-day “omer” period).  We can undergo a similar process of spiritual development each year during these 49 days (how to do that is beyond the scope of this website). According to our tradition, the Israelites in Egypt had sunk to the 49^th level of spiritual impurity (tum'a). The Israelites had to raise themselves in 49 daily stages to be worthy of receiving the Torah.  Several books and siddurs portray the 49 days of the omer as corresponding to the Seven Sefirot embedded in the seven weeks.  This awareness can help us work on and maximize the power inherent in each day of the omer to fix that particular sefira in ourselves. We thus relive this transition from slavery to freedom and the service of God each year as we try to perfect our midot (personal characteristics) to again be worthy of receiving the Torah on Shavuot.

 
Symbolism of the Shavuot Offering
In the Temple in Jerusalem, the only communal sacrifice of leavened bread was on Shavuot. Leavening in dough is compared to arrogance in humans (people puff themselves up to look more important than they actually are). During Passover we destroy, and refrain from eating, leaven--just as we try to destroy/remove arrogance from our personalities. After Passover, we continue to work on our personal traits (midot) until we reach Shavuot, when we celebrate receiving the Torah.  At Shavuot, we Jews have a right to feel important, since we are spiritually elevated by virtue of having been given the Torah.
 
Shavuot: Universal Customs
The universal custom is to eat at least one dairy food during Shavuot.
Possible reason  At the time the Israelites received the Torah, they did not have any kosher meat (they had not been required to eat kosher until then) and so the only food they were permitted to eat was dairy food.
Another universal custom is to stay awake all night (if possible) studying Torah.
 
Shavuot: Symbols
Unlike other Jewish festivals, Shavuot has no concrete symbols and no specific unique commandments/mitzvot, other than sacrifices that were brought in the Temple in Jerusalem.

Introduction to Fast Days
The purpose of Jewish fast days is to make us reflect on our behavior and improve it by:

• Eliminating negative actions and thoughts, and
• Taking more care in our observance of the commandments.

God told the Jewish people on many occasions that He did not want their pointless sacrifices or fast days but rather wanted the Jews to improve their behavior. If people fast but still have reprehensible behavior, the people have missed the point and purpose of bringing sacrifices and having fast days.
All fast days may be circumvented for health reasons. Consult a rabbi.
Fast days come in several varieties:

• Major fast days: Yom Kippur and the Ninth of Av (Tish'a B'Av). 
• Minor fast days: There are four minor fast days; see below.
• Fast for First-Born
• Individual Fasts

The Major Fasts
Yom Kippur and the Ninth of Av begin before sunset and are both slightly longer than 24 hours. Yom Kippur is a festive day while, on the Ninth of Av, Jews mourn for the destruction of both Jerusalem Temples (the first was destroyed by Babylonians; the second, by the Romans). On both fasts, it is forbidden to:

• Eat or drink.
• Wear leather shoes (but you may wear any other clothing made of leather).
• Bathe (or even to wash anything more than fingers; you may not use a deodorant--not even a spray type--since it is similar to washing).
• Have marital relations.
• Use cosmetics or body scents.

The Minor Fasts
The four minor fasts begin 72 minutes before local sunrise. They technically end at dark but functionally end after ma'ariv (and for the Fast of Esther, after hearing the megila). Unlike most times in the Jewish calendar, this 72 minutes is normal time and NOT based on the current length of the day (sha'a zmanit):

• Fast of Esther (Ta'anit Esther): Day preceding Purim (or sometimes earlier).
• Fast of Gedalia (Tzom Gedalia): Usually the day after Rosh Hashana.
• Tenth of Tevet (Asara b' Tevet):
• Seventeenth of Tamuz (Shiv'asar b'Tamuz): Beginning of the Three Weeks of semi-mourning beforeTish'a b'Av.

On all fast days, eating and drinking are forbidden. The Tenth of Tevet and the Seventeenth of Tamuz additionally have the same restrictions as the Nine Days. So you may wash or bathe on the Fast of Esther and on Tzom Gedalia but not on the Tenth of Tevet and the Seventeenth of Tamuz. (See Nine Days: Restrictions).
Note On a fast day that has been delayed for Shabbat, there may be leniencies for:

• The mohel, sandak, and father of a baby getting a brit mila to eat after mincha.
• Pregnant or nursing women (this leniency applies to eating throughout the day).

Fast for First Born
Fast for first-born males 13 years old and older, on the day before Passover. This includes first-born cohanim and Levites (levi'im). The fast begins 72 normal minutes before sunrise and ends with kiddush at the seder. However, the widespread custom is to attend a siyum on the day before the first seder so that the first-born men do not need to fast on that day.
 
Personal Fasts
Fast by a groom and bride on their wedding day is an example of personal fasts. This fast begins 72 normal minutes before sunrise and ends with drinking wine under the chuppa.

To be able to say the special blessings after a festive sheva brachot meal, there must be present at least:

• 10 Jewish males at least 13 years old, and
• One person (male or female) who was not present at the wedding or at

  any meals since then with the bride and groom.
