If you choose to use Satan's time for Yahweh's appointments, it is guaranteed that you will be worshiping on a false Satanic Sabbath. It can be no other way. Occasionally, they will align accidentally, but you will still be following (obeying) Satan and not Yahweh. It doesn't matter if you pick Friday, Saturday, Sunday or any other day of Satan's week. NONE will be Yahweh's Sabbath. Yahweh's Sabbath will be on some other, different day.
All the controversy over Saturday vs. Sunday is amusing because BOTH are incorrect. BOTH are using Satan's changed, counterfeit time and NEITHER can be right.
Does it matter which day we meet Yahweh for worship? I can't answer that for you. You need to decide. But, the choices are not between Friday, Saturday or Sunday. The choice is between Yahweh's week and time or Satan's.
And all the world wondered after the beast. Revelation 13:3
