• May not do this on Shabbat.
• Must have already paid before sunset. 
• May not open a door that will cause a light to turn on or do any other melachot.
• If you have already traveled outside techum, you may move only 4 amot (85” or 116 cm) away from the vehicle, unless the driver leaves you off in an enclosed domain (any area surrounded by walls or an eruv), in which case you may go anywhere in that domain.
• If you had not gone outside of techum, you may go anywhere in the domain and you may also go up to 2000 amot (3,542 ft. or 1,080 m) outside of the domain.

• Before sunset on the first day of a Jewish festival, and
• After dark on the Jewish festival's second day (except when the second day coincides with Shabbat!).

• You may light only from an already-burning flame.
• You may not light Jewish festival candles after sunset on Friday nor on the evening before Yom Kippur begins.

• First night of Jewish festivals
• Night of seventh day of Passover
• Night of Shmini Atzeret.

• First day of Jewish festival
• Second night of Jewish festival
• Second day of Jewish festival
• Seventh day of Passover
• Eighth night of Passover
• Eighth day of Passover
• Shmini Atzeret day
• Night and day of Simchat Torah.

• For evening kiddush for a first-night (d'oraita) Jewish festival, a minimum of 4 fl. oz. (119 ml) of wine must be blessed on and at least half must be drunk.
• For evening kiddush for a second-night (d'rabanan) Jewish festival, a minimum of 3.3 fl. oz. (99 ml) of wine must be blessed on and at least 2.0 fl. oz. must be drunk.
• For the evening meal, as on the first two Shabbat meals and for all required Jewish festival meals, a minimum of 1.9 fl. oz. (56 ml) of bread must be eaten within four minutes.

• Morning kiddush requires a halachically legal “meal” with these elements:
  • Blessing on a minimum of 3.3 fl. oz. (99 ml) of wine (or other beverage),
  • Someone's drinking at least half the beverage, followed by
  • Eating at least 1.3 fl. oz. (39 ml, or 1/6 cup) of some type of mezonot within four minutes. 
    Note If you drink at least 3.3 fl. oz. (99 ml) of wine within 30 seconds, you do not need to eat mezonot.
    Note You do not need to drink the wine or other kiddush beverage to fulfill “establishing a meal.” You may hear kiddush and then simply eat the required amount of bread or mezonot. This applies to Shabbat or Jewish festivals, evening or morning.
     

• The real meal (kovei'a se'uda) requires eating at least 1.9 fl. oz. (56 ml) of bread (or matza during Passover!) within four minutes. It must include enough food to satiate. 
  Note You can simultaneously fulfill the requirement to “establish a meal” and to “eat a meal” by eating one (the same) piece of bread.

1. Make Kiddush
   Say, or hear, the three Jewish festival evening kiddush blessings/segments:
   1. Borei pri ha'gafen (if on wine or grape juice—preferred option), OR
      Ha'motzi (on two challot if you have no wine or grape juice, since no chamar medina is allowed for Jewish festival evening kiddush; see Jewish Festivals: Kiddush: Challot for Kiddush) AND
   2. Asher bachar banu mi kol am.... mekadeish Yisrael v'hazmanim, AND
   3. She'hecheyanu on all Jewish festival nights, except the last two nights of Passover.  So say she'hecheyanu on:
      • Both nights of Rosh Hashana (in or outside of Eretz Yisrael),
      • First two nights of Passover (1 night in Eretz Yisrael),
      • Both nights of Shavuot (1 night in Eretz Yisrael),
      • First two nights of Sukkot (1 night in Eretz Yisrael), and
      • Nights of Shmini Atzeret and Simchat Torah (same day in Eretz Yisrael).
      Note There is never any requirement on an indvidual to drink kiddush wine (except at the Passover seder), but the kiddush wine must be drunk by one or more persons.
      Note A woman who had said she'hecheyanu when she lit the Jewish festival candles does NOT say she'hecheyanu again if she makes kiddush for herself, even when making kiddush at the Passover seder.
      Note There is no need to eat a new fruit after saying she'hecheyanu on the second night of  Shavuot, Passover, or Sukkot. This is not comparable to Rosh Hashana, since the second festival night was instituted due to uncertainty of the actual date of the holiday, while Rosh Hashana is considered to be one single, long day.
2. Establish a halachic “meal” (kovei'a se'uda).
   For how to establish a halachic meal, see Introduction to Jewish Festival “Eating a Meal” Requirements.

• Siddur, machzor, or chumash to use on that day.
• Permissible medicine for use on that day. 

• Lower the temperature when an air conditioner compressor is running, and
• Raise the temperature when the compressor is off.

• Putting slips of paper in the book (but only if the slips were torn before the Jewish festival began), or
• Bending the corners.

You may wipe a stain off of your face or hands onto a cloth or piece of paper if you do it to clean your face or hands on Jewish festivals (and Shabbat), but not if you want to color the cloth or paper.

• You may walk into one that prevents a door from closing.
• You may not walk into one that causes the door to open.

• The elevator stops at all floors, or
• A non-Jew pushes the button in order to ride the elevator himself.  But:
  • You may only get off on the floor he or she has stopped at (he or she may not push a button for a different floor for you).
  • You must enter the elevator while the door is already opened but has not yet begun to close (since your presence keeps the door open but does not cause it to open).

• No melacha is involved, and
• It does not appear to be for healing (refu'a) or health purposes.

• UP when running, and
• DOWN or OFF when not running.

• You need the heat elsewhere, or
• You need to use the space where the heater is standing.

• Transfer the laundry from one halachic domain to another (hotza'a), or
• Give the impression that the laundry had been washed on the Jewish festival (mar'it ayin).

• Plug or unplug the plug from the wall.
• Turn the light on or off.

• You need the space where the lamp is situated, or
• The cord is in the way and you want to remove it so someone doesn't trip.

• Open

• From within techum Shabbat, AND
• By a non-Jew. 

• Printed on Shabbat or a Jewish festival, OR
• Brought from outside the techum Shabbat, OR
• Delivered by a Jew.

• You do not need a ticket, and
• They are not playing particularly for Jews.

• Sponge (even if it is on a handle), 
• Dish rag, or 
• Scrubbing pad (pad that holds water and, when used, the water gets squeezed out).

You may talk about weekday subjects on Jewish festivals if what you are discussing already happened, but you may not discuss plans to do activities that involve any type of melacha, even d'rabanan.

You may tear paper, plastic, foil, or other wrappers around food in order to eat that food on a Jewish festival.

You may tear plastic and foil (but not paper) around napkins, plasticware, etc., that you need on Jewish festival.

But you may not:

• Do so if you will inevitably tear through any words or pictures on the package.

• Use scissors.

   

Except for wrappers for food or eating utensils, do not tear paper, foil, toilet paper, parchment paper, plastic wrap, paper towels, etc., on a Jewish festival.

Note If there is a perforation, that makes the tearing worse.

Note If you do not have any torn toilet paper, tear it is an unusual way:

EXAMPLES

• Tear using the back of your hand.

• Spread the toilet paper across your knees and then spread your knees apart.

Reason The trees are muktza.

• You may sew or lay bricks or other such labors, but not if you are an expert or professional in those fields and you are doing expert work.
• Skilled writers and artists may not do their professional writing, calligraphy, or drawing (even for free!) on chol ha'moed. They may not do calligraphy or sofer work (Torah, tefilin, mezuza), but they may write normally.
• If you are not a professional writer or expert craftsman/artist, you may write on chol ha'moed but the preferred practice is to use a shinu'i --an altered method of writing, such as:
  • Using your other hand,
  • Holding the pen/pencil differently from normal, or 
  • Writing diagonally across the paper.

• You normally shave every day, and
• You shaved before the Jewish festival began.

• If you forgot:  Repeat the amida of Rosh Chodesh shacharit or mincha.
• If you are not sure:  Repeat the amida with the condition that if you had said ya'aleh v'yavo the first time, the second time is a voluntary prayer (tefilat nedava).

• “Ketiva V'Chatima Tova”

• “L'Shana Tova Tikateiv V'Tichateim”

• “Gmar Chatima Tova”

• “Gmar Tov”

• Make kiddush,
• Wash your hands,
• Say ha'motzi, and
• Eat bread.

• Charata  Regretting what we have done and feeling bad about it.
• Vidui  Recognizing and admitting that we have done something wrong.
•  Kabala  Resolving not to repeat that mistake.
• Azivat hachet  Being in the same situation as before but avoiding doing the sin.

After Yom Kippur, say the full havdala. 

Note You must light a candle from a flame that was burning since before Yom Kippur began. If you do not have one, skip the blessing on the flame.
If Shabbat coincides with Yom Kippur, you should light the candle from a flame that was burning from before Shabbat began. If you do not have one, you may light a new flame after Shabbat and Yom Kippur are over. Don't say the blessing on spices.

• Palm branch: Spine.
• Myrtle leaves: Human eyes.
• Willow leaves: Human lips.
• Etrog: Human heart.

• Etrog smells nice and tastes nice--like a tzadik who is knowledgeable in Torah and does mitzvot;
• Myrtle smells nice but does not have a good taste--like a person who does mitzvot but is not knowledgeable in Torah;
• Palm tree (date palm) has a nice tasting fruit but no scent--like someone who has knowledge but lacks mitzvot;
• Willow does not smell nice nor has a good taste--like a person who has neither.
