In Genesis 1:2 it is stated, " And darkness was upon the face of the deep."
In Genesis 1:3 it is stated, " And God said, Let there be light: and there was light."
In Genesis 1:4 it is stated, " God divided the light from the darkness."
In Genesis 1:5 it is stated, " and God called the light Day, and the Darkness he called Night. And the evening and the morning were the fist day".
To the Jews, the people of God, the Sabbath begins at 6pm on Friday and ends at 6pm on Saturday. This is the evening and the morning that the Jews consider a day of a 24 hour time period. Their Sabbath doesn't begin at 12:01 am (1 minute after mid-night) on Friday, but at the beginning of night 6pm on what we Gentiles call Friday.
I believe you are correct, but yet do we define God's timing to mans timing as God's ways are not our ways. There is no way to define God's timing in all He has done.
