Shabbosim
Shabbat is from sunset on Friday to sunset on Saturday, every week.
Shabbat ends in New Jersey on Saturday at sunset. You can check the specific time for today by looking up the sundown time in your location.
Blowing the Shofar is a form of musical instrument, and playing musical instruments is generally prohibited on Shabbat to honor the day's rest. However, there are exceptions to this rule, like during the High Holidays when it is allowed to blow the Shofar.
There are two main aspects to Shabbat observance: what we do and what we don't do. What we don't do: we're not permitted to work on the Shabbat (Exodus ch.20). This includes 39 categories of productive interaction with the world, such as planting, writing, kindling fire, etc. (Talmud, Shabbat 73b). What we do: candles are lit, customarily by the lady of the household, around 20 minutes before sunset on Friday afternoon. We then attend synagogue for the Friday afternoon prayer (mincha), the kabbalat Shabbat (ushering in of the Shabbat), and the Shabbat evening prayer (maariv). On Shabbat morning, we again attend synagogue. The services are longer than on weekdays and include prayers as well as reading the weekly Torah-portion. There's often a kiddush (refreshments) afterwards, and congregants have a chance to schmooze (to talk). Towards the late afternoon, there's another (short) service (Shabbat mincha). After Friday night services and on Shabbat morning after services, we come home, often with guests, make kiddush (blessing over wine), and have a leisurely multi-course Shabbat meal including singing and words of Torah. Customarily, that week's Torah-reading (parsha) will be a topic of conversation; and the children of the family will have a chance to speak of what they've learned in school. After that, Shabbat is a quiet time: no phones, radio or TV (etc.), just schmoozing, taking walks, visiting friends, reading, learning Torah, playing board games, etc. Husband and wife, in particular, finally have a chance to be together after a hectic week.
A Shabbat service typically lasts around 1-2 hours, although this can vary depending on the specific customs and traditions of the synagogue or community holding the service.

The basic necessities for observing Shabbat are:Shabbat candles (at least 2) and an appropriate candle holder.Wine (grape juice is fine if you don't like wine) that is certified kosher.Two challot (plural of challah).Additionally, it's expected that we serve at least two different kinds of meat for the Shabbat dinner (Friday evening) [unless you are a vegetarian].And, as no cooking is allowed once Shabbat starts, many people use a slow cooker or Shabbat compliant oven (one that doesn't auto-shut off) to prepare a hot meal for lunch Shabbat day (Saturday) in advance.
They prepare their children for Shabbat and light the Shabbat candles.
