On the seventh day God rested...The 7th day is the Sabbath.
That is, at the end of the 6th day, which is when the sun sets, until the end of the 7th day, when the sun sets, is the Sabbath...Between these two sunsets is the 7th day.(Moses hadn't invented clocks back then so forget about midnight)
The only problem is that the Beast of the book of Revelations
has changed dates and times (Ref. The Catholic Church)
We live our lives on a Gegorian calander which is based on the cycles of the sun. It is a Solar calander. The Sabbath is based on the cycles of the moon and is called a Lunar Calander
