A HOLY DAY

"Shabbos" or "Shabbat"
"Shabbos" - the Ashkenazic pronunciation, or "Shabbat" - the Sephardic pronunciation, either way it is the Hebrew word for the seventh day of the week; known in English as the "Sabbath." The root of the word means "to rest or desist." Shabbat, the Divinely appointed day of rest, begins (18 minutes) before sundown on Friday and ends Saturday night when three stars appear in the sky. (About 45 minutes to 1 hour after sundown.)

The very first thing in all of the Torah to be called holy is Shabbat.
The Torah states (Bereishit / Genesis 2:1-3):
"By the seventh day, G-d completed His work which He had done... G-d blessed the seventh day, and He made it holy..."

What is the holy Shabbat?

We could spend hours and write pages of deions, yet we could not fully explain Shabbat. Shabbat has to be experienced to understand it.

Lets go back to the creation of the world.

For six days Hashem created the heavens and the earth. On the seventh He rested. That's what Shabbat is all about. Six days a week we go about our lives working and playing and doing what it takes to live in this world. But by the time the sun sets on Friday night, the hustle and bustle of the world is put behind us and the Shabbat celebration surrounds us. On Shabbat we don't perform any work. Instead, we proclaim that Hashem is the master of all creation.
