If The Divine Name is not important, then perhaps which day you keep is also not important. Consider this thought as you read the following:
Prophets and Kings page 678
In the time of the end every divine institution (Calendar) is to be restored. The breach made in the law at the time the Sabbath was changed by man, is to be repaired.
But YHVH Elohim has set His Seal upon His Royal Requirement. Each Sabbath institution (calendar), both true and false, bears The Name of its Author, an ineffaceable Mark that shows the Authority of Each. S.D.A. Bible Commentary Vol. 7-CN- REV14-CT- Revelation-PR- 07-PG- 977
So what names are on two calendars? The Sabbath “institution” infers a “calendar” by which to determine days, which is set out in Genesis 1:14-17, and in Exodus 20:8 accurate on the tables of stone, the 4th Commandment, in today’s bibles contain “the breach”. So to find the correct “Sabbath Institution” you will need His Correct Name, to locate It.
Leviticus 1:1 in the Hebrew Masoretic text, displays an embedded hidden calendar, the lunar calendar, with His Name YHVH, each letter preceding each sequence of 7 letters, 4 sequences of 7, preceded by each Letter of His Name, the Tetragramaton.

The false, saturday, is preceeded by “satur”, in ancient chaldee, “Satyr” means “Satan”
