The Scriptural Sabbath is not necessarily on Saturday. Unless you are retired or independently wealthy, keeping Yahweh God’s calendar is not possible for us at this time. The actual Sabbath occurs on a different day every year as the annual count always starts with the beginning of Spring. The best we can do is take 24 hours every seven days for rest.
Hebrews 4:9 “There remains therefore a Sabbath rest for the people of God.”
