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.
Here is further background information:
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.
It depends on the person, but traditionally, Jews celebrate the Sabbath from Sundown Friday night, to Sundown Saturday night.
Saturday is the Sabbath in Judaism. Orthodox (and some non-orthodox) Jews will not work. Many non-Orthodox Jews will work, but still remember the Sabbath day in their own ways. (And yes, there are some Orthodox Jews that work on Saturdays, but they do not advertise this fact).

Saturday.
No, the day for the Sabbath is set in the 10 commandments as Saturday.
Jews all over the world, including Russia, observe the Sabbath from Friday sundown to Saturday night.
Why yes, it is very innappropriate to us Jews.
Saturday
It should actually be Saturday and not Sunday. Saturday is the Sabbath for Jews and some Christians, but Catholics and most major Protestant sects observe Sunday as the Sabbath, but Catholics may attend Saturday evening Mass , as the Jews observe from sundown Friday to sundown Saturday, Catholics now may attend Mass from Saturday thru Sunday.
The Sabbath begins Friday at Sundown, and ends on Saturday at Sundown. This is true for all practicing Jews, not just Orthodox Jews.
Yes, but only after Shabbat has ended (after sundown on Saturday night).
Any marriages on Shabbat are strictly prohibited by Orthodox and Conservative Jews, and by reason of custom, completely discouraged by Reform Jews. Most Jews that marry on Saturday are secular Jews, and therefore would not be married during a prayer service.
