Here's more:

The Jewish Sabbath is from Friday sundown until Saturday after twilight. Its origin is in the Torah (Genesis ch.2, Leviticus ch.23, Exodus ch.20 and many other passages).

The Sabbath is considered in the Jewish religion to be a day blessed by God (Genesis ch.2), a day of rest (Exodus ch.20, ch.31), and a day of strengthening ties with the family, the community, and with God.

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.

"You too, thank you!"

Yes.

Shabbat, the Jewish Sabbath, starts at sundown on Friday evening end ends at nightfall on Saturday evening. Note that sundown occurs when the sun sets, while nightfall is defined by the appearance of 3 fixed stars in the sky (or about an hour after sundown if you can't see the sky). Jewish calendars are frequently printed with the time of day of each of these in larger Jewish communities, and nowdays, you can find apps that use GPS to give these times wherever you are.

They symbolise light. They mark the presence of the Shabbat itself, and also hint to the Divine presence.

Generally the havdalah spice is clove or myrtle, but any sweet smelling spice can be used.

Sabbath begins at sundown on Friday night. Since the length of a day changes every day, this is not a consistent minute or hour.

There are a great number of things you can do. The following list has the most commonly done things: Pray in a Synagogue, Eat Meals, Socialize with your Family, Read, Sleep, Play Games, and Study.

Of course children are allowed to play during Shabbat! The one restriction is that their play can't involve creation such as colouring and writing or destruction such as cutting paper.

Saturday at sundown

Whether or not it's celebrated, observed, or even acknowledged, the Shabbat is

the seventh day, which, in Judaism, corresponds to Saturday.

As in many other ancient cultures, each day in Judaism is considered to begin at

sundown and end at the following sundown. Accordingly, the Shabbat begins at

sundown on Friday evening and extends until sundown on Saturday evening.

Those who observe it, whether in the synagogue, in their homes, or in some

part of their private lives, observe it during that period of time.

The spice box is the box used for the Havdalah service after Shabbat.

"Happy Sabbath" (though this is not a standard greeting for the sabbath. It would be more appropriate to say Shabbat Shalom, "a peaceful sabbath").

They prepare their children for Shabbat and light the Shabbat candles.

In the synagogue and in the home

Havdallah is a religious service where we say goodbye to Shabbat (The Sabbath) for the week.
