The Five Special Fruits do not combine in volume with non-special fruits for the after-blessing of al ha'eitz if eaten sequentially or even interspersed with each other.
Example
Situation
You ate a date and then ate the remainder of 1.3 fl. oz. (39 ml, or 1/6 cup) of cherries.
What To Do
Say:

• Fore-blessing of borei pri ha'eitz over the date (and cherries).
• After-blessing of borei nefashot on all the fruits.

If you are not sure if you said ANY blessing in ANY category, don't repeat it.
 

When moving to a community with customs different from your own, adopt the customs of your new community but ONLY:

• If you intend to stay in that new community, and
• If the entire community follows the same customs.

Some communities have the custom of an onen's saying kaddish.
NOTE When a person's parent dies on or just before (erev) Shabbat or a Jewish festival, a daughter of any age should not be told until after Shabbat or the festival is over. A son should only be told if he is 6 years old and above and the custom in that community is to say kaddish as an onen.

The volume of special and non-special fruits DO combine for the after-blessing if:

• They are considered to be one food, AND
• The main component is the Special Fruit.

You may not eat non-special fruits sequentially with or even interspersed with the Five Special Fruits in order to make the minimum volume for saying the after-blessing of al ha'eitz.

Three Shabbat Meals
We are required to eat three Shabbat meals, as a rabbinic (d'rabanan) enactment to enjoy Shabbat (oneg Shabbat). The first Shabbat meal must be at night and the remaining two must be during the day (the third meal must be eaten after halachic midday). Friday night dinner and the first meal on Saturday are preceded by kiddush. For the first two Shabbat meals, say ha'motzi over two complete loaves of bread, each of which is at least 1.3 fl. oz. in volume. For the third meal, the ideal is to use two complete loaves of bread, but the requirement of eating the third meal can also be fulfilled by eating any food other than salt or water.

Source of Saying Shabbat Kiddush

• Saying kiddush on Shabbat night is a commandment from the Torah (d'oraita).
• Saying kiddush on Saturday morning is a rabbinical (d'rabanan) enactment.

Note If you did not say Friday night kiddush, you must say that version of kiddush on Shabbat morning and it is then a requirement from the Torah (d'oraita). Do not begin with va'yechulu; instead, begin with borei pri ha'gafen and say the second blessing of kiddush.

Source of Kiddush Location
Saying kiddush at the place where you will eat your meal is a rabbinical (d'rabanan) enactment.

Shabbat Kiddush-Meal Quantities: Evening

• For evening kiddush, a minimum of 4 fl. oz. (119 ml) of wine must be blessed on and at least half must be drunk.
• For the evening meal, as on Shabbat lunch and all required Jewish festival meals, a minimum of 1.9 fl. oz. of bread must be eaten within four minutes.

Shabbat Kiddush-Meal Quantities: First Meal on Saturday
Shabbat day first meal has two separate eating requirements.  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 mezonot; 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.
1) Morning kiddush requires a halachically legal “meal” with these elements:
      a) Blessing on a minimum of 3.3 fl. oz. (99 ml) of wine (or other beverage),
      b) Someone's drinking at least 2 fl. oz. of the beverage, followed by
      c) Eating at least 1.3 fl. oz. (39 ml, or 1/6 cup) of some type of mezonot (or bread) 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 kiddush “meal” does not have to satiate.
Note If you have not fulfilled the requirements for kiddush, you may not eat other foods, such as fruit or fish at a kiddush.

2) The real meal (kovei'a se'uda) of Shabbat lunch requires eating at least 1.9 fl. oz. (56 ml) of bread (or matza during Passover!) within four minutes. It should 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.
For details on fulfilling the first two meals' requirements, see Shabbat: Kiddush.

Shabbat: Eating a Meal Requirement: Third Meal
For details on fulfilling the third meal's requirements, see Shabbat: Third Meal (Se'uda Shlishit).

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

As on Shabbat, don't fast on Jewish festivals (except Yom Kippur!) past halachic midday.

• If you will not finish shacharit before halachic midday, you should eat or drink earlier in the day, even before you begin shacharit—water can be sufficient for this purpose.
• If you will finish shacharit, but not musaf, by halachic midday:
  • Finish shacharit,
  • Make kiddush,
  • Eat some mezonot, and then
  • Return to say musaf.

If you fell asleep for more than 30 minutes in the middle of a meal:

• Wash again and say ha'motzi again, and then say birkat ha'mazon, OR 
• Eat other items with a fore-blessing and after-blessing (since your previous eating is finished).

• Say birkat ha'mazon if you are:
  • Finished eating, and
  • Not hungry again, after having been satiated at the meal.
• Do not say birkat ha'mazon if you are
  • Finished eating, and
  • Hungry again (after having been satiated at the meal), as the original snack or meal is irrelevant to any after-blessing now.

All animals are muktza on Shabbat, even pets, since they do not have a practical use. Moving the animal or its fur or picking up an animal is a violation of muktza.

You must repeat the after-blessing for mezonot, wine/grape juice, or any of the Five Special Fruits if you ate items from more than one of those categories, said the after-blessing for just one of them, and forgot the other. 

If the leader gets to kedusha on Shabbat or Jewish festival morning and you are saying the amida, you must:

• Pause until the leader has finished the blessing after kedusha (ha'el—or ha'melech—ha'kadosh), and then

• Resume your amida.

During birkat cohanim, you must:

• Pause in your amida until the end of birkat cohanim.

EXCEPTION Do not pause, even if the leader says kaddish or kedusha, if doing so will delay you past the fourth hour.

• Unwrap the excess strap from your palm and wrap it three times around your middle finger while saying the three “v'eirastich li” phrases, one for each wrap.
• Wrap the strap around your palm in the shape of the Hebrew letter “shin.”
• Wrap the excess around your palm and tuck in the end of the strap to keep it tight and out of your way.

If you fell asleep for more than 30 minutes in the middle of a meal:
Step 1: Wash your hands the Three-Times Method to remove the tum'a of your sleep.
Step 2a: To Continue Eating
To continue eating in this case, since the previous blessings and food are no longer relevant (due to hesech da'at), you may:

• Wash again and say ha'motzi again, and then say birkat ha'mazon, OR 
• Eat other items with a fore-blessing and after-blessing (since your previous eating is finished).

Step 2b: If You Are Finished Eating

• Say birkat ha'mazon if you are:
  • Finished eating, and
  • Not hungry again, after having been satiated at the meal.
• Do not say birkat ha'mazon if you are
  • Finished eating, and
  • Hungry again (after having been satiated at the meal), as the original snack or meal is irrelevant to any after-blessing now.
