If you shave regularly (can be every day or a few times each week), you may shave after 30 days but not within 30 even if for non-parent and certainly not for a parent. If you normally grow a beard, you may not shave until 3 months have passed since the last time you trimmed your beard (and as long as it is more than 30 days from the day shiva began for the parent).
In case of a large financial loss, consult a rabbi.

Say she'hecheyanu the first time you light Chanuka candles each year:

• Even if your first time is the second or subsequent nights.
• Even if someone lit for you the previous night.

 

You must say the blessing which was designed to be said on each type of food. B'diavad, a lower level blessing will still cover the food.
From lowest to highest level, here are the food fore-blessings:

• She'hakol,
• Borei pri ha'adama,
• Borei pri ha'eitz (on common fruits),
• Borei pri ha'eitz (on the Five Special Fruits)

You may walk between bushes or trees, even if they are close to each other, and you may use your body to make space for yourself to walk. But you may not push the trunks or branches away using your hand.
Reason The trees are muktza.

Eruv walls must total more than 50\% of the eruv border on each side, so that most of the expanse of the eruv is enclosed, either by an actual wall or by the form of a doorway (tzurat ha'petach), with no gate or gap over 10 amot (about 16' 8”, or 5 m) wide.
Note  In order to count as part of a border for a private domain, any doorway, gateway, archway, etc., must be intended to be a doorway, gateway, archway, etc.--and not there merely for decoration or function (as in supporting something above).
 

Hot, clean, dry utensils of opposite genders, even if touching each other, both remain kosher.
Hot, clean, wet utensils of opposite genders touching each other are both not kosher. 
SITUATION One of the utensils had not been used in less than 24 hours before the contact.
STATUS That unused utensil becomes not kosher. However, even if the other utensil had been used in less than 24 hours before the contact, it remains kosher.

 

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. 

Source of Saying Jewish Festival Kiddush
Some kiddushes are commanded by the Torah (d'oraita); the others are from Chazal (d'rabanan), as follows:

• Night of seventh day of Passover
• Night of Shmini Atzeret.

Kiddush d'Rabanan

• 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.

Source of Jewish Festival Kiddush Location
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.

You should give charity frequently, even if that means giving smaller amounts at each giving.

You are not required to check tzitzit on a talit katan or talit gadol each day. 
Reason We assume, based on the norm (chazaka), that the tzitzit are OK.
But it is a good idea to check them before saying the blessing over them each day.

Nail clippings, even from children and non-Jews, have ru'ach ra'a and need to be disposed of. The simplest way is to flush them down a toilet or wash them down a drain (but don't put them into the garbage).

If you bake several units of dough in one pan and they expand into each other, you may not break them apart after baking and use them as separate challot. If they only slightly touch each other, you may separate them and use them as individual challot.
 

Torn
In checking tzitzit, determine:

• Are any loops torn?
• Are 8 strings visible on each corner?

If you cannot see 7 strings due to one or more having been torn off, consult a rabbi.

Tangled
There is no problem if tzitzit are tangled. However, to untangle them:

• Is a superior way to fulfill the mitzva, and 
• Allows you to easily check them to see if there are 8 tzitziyot.

Frizzy
If any tzitziyot are so frizzy that the individual tzitziyot cannot be distinguished, they are invalid (pasul).
Note To prevent frizziness during laundering, wrap the tzitziyot tightly in a rubber band before drying them in a dryer, or hang them to dry.
Note

• If the hanging end of a tzitzit string breaks below the lowest knot, the string is kosher.
• If more than one string breaks, or if one string breaks above the lowest knot, consult a rabbi since the tzitzit may not be kosher.

The mesader kidushin asks the witnesses if they are related to either the bride or groom or each other. He then asks the bride and groom if they want these and only these witnesses to be their witnesses.

There is no time limit on when alenu may be said. Alenu should be said after each prayer service.

To remove from your property a fruit tree that produces at least 46 oz. of fruit each year, you must sell the tree to a non-Jew. The non-Jew may then remove it.
