If there is not enough wine or grape juice for Shabbat (or Jewish festival kiddush) and havdala:

• Set aside the first cup for havdala; then, if there is one more cup,
• Use it for the morning kiddush.
• See How To Do Shabbat Daytime Kiddush and How To Do Shabbat Evening Kiddush .

 

Kos pagum means either:

1. "Physically damaged or broken drinking utensil”: You may not use such a cup for kiddush l'chatchila. OR

2. Cup of wine, grape juice, or any beverage that has been drunk from.  This beverage may not be used for a kos shel bracha until at least a small amount more of some beverage has been added.

We are required to eat two meals on Jewish festivals, each preceded by kiddush, one in the evening and one in the morning. For both meals for each Jewish festival day (and all three meals on Shabbat), say ha'motzi over two complete loaves of bread, each of which is at least 1.3 fl. oz. in volume.

Saying Jewish festival kiddush at the place where you will eat your meal is a rabbinical (d'rabanan) enactment.
Jewish Festival Kiddush-Meal Quantities: Evening

• 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.

Eating Requirements for Jewish Festival Morning Kiddush
There are two separate eating requirements during the daytime. They may be combined (say/hear kiddush and start the main meal right away) but are often done separately (say/hear kiddush and then eat some light foods and beverages; the main meal is eaten later in the day).
Note Since eating and drinking requirements on all morning kiddushes (both Shabbat and Jewish festivals) are d'rabanan, the required beverage amount for morning kiddush is only 3.3 fl. oz. (99 ml) instead of the d'oraita 4 fl. oz. (119 ml) (which is required for kiddushes for Shabbat evening and all first-night Jewish festivals).

• 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.

The seder is the only time in the year that you must drink most of your cup (rov kos) of kiddush wine. (For kiddush on Shabbat and Jewish festivals, you need drink only 2 fl. oz., or 59 ml).  So if you have a cup larger than 4 fl. oz. (119 ml), you may have to drink a lot of wine--more than half of each cup for four cups! 

You do not need to close the wine bottle or cover the other wine cups while the first of several people says kiddush, whether on Shabbat or Jewish festivals.

1 Revi'it = Usually 3.3 fl. oz. (99 ml); but 4 fl. oz. (119 ml) for:

• Any food requiring bracha achrona.
• The four cups of wine at the seder.
• Kiddush for Shabbat and Jewish festival nights.

 
1 Log = Volume of 6 eggs = 4 Revi'ot (a revi'it is 1/4 of a log)  
1 Kab = 4 Login  
1 Se'ah = 6 Kabin
 
40 Se'ah = Volume equivalent to 3 cubes, 24 ½” (61 cm) on each side; minimum requirement for mikva = about 192 gallons/750 liters  

1 fl. oz. = 1.77 cu. inch (about the size of a golf ball)

If a non-Jewish business makes a mistake in your favor, it is considered a saintly trait to correct the mistake. It is especially a kiddush HaShem to return the money to them if they know that you are Jewish.

At the Passover seder, all Jews above the age of bar mitzva or bat mitzva (including women--unlike on other Jewish festivals) must drink wine for kiddush and for the other three times in the seder when the borei pri ha'gafen blessing is said.

You must eat a second meal on Jewish festival (or Shabbat) day with 1.9 fl. oz., or 56 ml, of bread--even if you already said ha'motzi and ate bread at kiddush.

You are required to return a lost object (hashavat aveida) to its Jewish owner if you can. This is a Torah commandment.

You must eat a second meal on Shabbat (or Jewish festival) day with at least 1.9 fl. oz. (56 ml, 1/4 cup) of bread--even if you already said ha'motzi but ate less than 1.9 fl. oz. of bread at kiddush.  

When you sit down in a sukka, only say the blessing leisheiv ba'sukka:

• If you are going to eat at least 1.9 fl. oz. (56 ml, or about 1/4 - 1/5 cup) of bread or mezonot within four minutes, OR
• Immediately after saying kiddush and before drinking the wine in anticipation of eating mezonot or bread, OR
• Before eating any food or beverage (except salt or water) when visiting any other person in his/her sukka.

Women and girls are generally exempt from time-dependent positive commandments (mitzvot), but they may perform these voluntary mitzvot and if they do, they do say the relevant blessings:

• Lulav
• Sukka
• Saying the full shema.

Women and girls may NOT do these time-dependent positive commandments (mitzvot):

• Kiddush levana
• Tefilin
• Tzitzit.

Do not say the blessing leisheiv ba'sukka except when you will eat bread or mezonot. Even drinking wine is not an exception, so do not say leisheiv ba'sukka even for havdala (unless you will also eat mezonot at the same time).
