Are weekday names a valid reason for Seventh Day Adventists to not worship on Sunday?

**God Names**
It is often heard from Seventh Day Adventists that they give a reason for not worshipping on Sunday because "it carries the name of the Sun god." But is this reasoning a valid one for deciding to worship on Saturday? A study of the names of the week confuses this logic. Sunday may (or may not) be the name of a sun god, but Saturday was named after the god/planet, Saturn! And in northern Europe the rest of the days of the week do also reflect the names of ancient gods: Woden (Wednesday), Thor (Thursday), Frei Friday) etc. Would this mean worship would not be allowed on those days? And in Hispanic countries, the weekend days are called "Sabado, Domingo". That is 'sabbath" and "the LORD'S DAY"! So in Spanish, what we call Sunday in English, is referred to, when translated, as *a day belonging to the Lord* ***for worship.*** [And many cultures do set aside that day for worship.] So would simply a name of the week in just a few languages be one legitimate or valid reason enough "to accept or reject" worshipping on that day?
