Shabbat isn't specifically a day of worship for Jews. Religiously observant Jews worship 3 times a day, every day, and 4 times on Saturday.
That being said, Havdalah service is one of the most beautiful religious services in my opinion and definitely worth attending.
We worship specifically on the Lord's Sabbath. The Sabbath was originally created for rest and worship. The Sabbath runs from Friday at sundown to Saturday at sundown.
Jews worship the sabbath from Friday eve to Saturday eve. Christians worship the Sabbath on Sunday. I am not sure about non-Christians, or non-Jews.
No, we worship God.Jews however, worship on the Sabbath Day more frequently and for longer than they do on other days.
Briefly, part 1 means that only necessary "work" like feeding livestock or dealing with emergencies should be accomplished on the Sabbath; if it is work that can possibly be done beforehand or afterward, do that. Part 2 may be restated "Sabbath rest is to forward--or "promote"--not to hinder Sabbath worship.
Friday at sundown is when the Lord's Sabbath begins. Sabbath is a day for worship, all activities on that day should be focused around God. This ends at sundown on Saturday.

rest and worship (i think)
Christians worship on Sunday, the first day of the week. Synagogues are normally open on the Sabbath or seventh day of the week (between sunset Friday and sunset Saturday). Most Christians would not worship in a synagogue.
Place of worship: the synagogue. Holy book: the Tanakh. Sabbath day: Shabbat (from Friday sunset till Saturday after twilight).
Sabbath is a day of rest or the time to worship and is observed differently in Abrahamic religion. It is stated that the SDA church can go to beaches on Sabbath.
Sabbath
If you're looking for praise & worship music from Black Sabbath, you won't find it. If you had a specific song in mind, you're probably thinking of "After Forever".
