Why Saturday?
The seventh day is a gift a rule protects.
In the Bible’s first story, God finishes the work and stops (Genesis 2:1–3). That is before any nation, and before any rule. Later the day is written into the Ten Commandments (Exodus 20:8–11), and Jesus says it was made for people, not people for it (Mark 2:27).
The seventh day of the week is Saturday. The Bible counts days from evening to evening (Leviticus 23:32), so the day runs from sundown Friday to sundown Saturday. Seventh-day Adventists keep it that way.
If it is only a rule
Tired people hear one more job. If it is a gift, the same sunset is a mercy: a whole day that is not for catching up.
Other Christians
Many Christians meet on Sunday. This page is not an argument against them. It answers one question: why Adventists keep Saturday.
This is a short answer from an independent guide. It is not an official lesson.
