The fact that Christendom celebrates "Easter" on Sunday is Evidence they understand it to be the 1st day of the week...hence, they know which day is the 7th.....
And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.
Matthew 16:2
But the seventh day is the sabbath of the LORD thy God:
Exodus 20:10
