> A quick check of Wikipedia suggests Arabic, Portuguese and Vietnamese, all use number-based systems to name the days of the week, and they are indexed from Sunday = 1. But yes, the other is more common. Most of the Slavic languages, and Chinese, among others, use indexed from Monday = 1.
For portuguese the name being number based has nothing to do with when the week starts, portugal is historically a very christian country and always had the week end on sundays, "and on the seventh day he rested", in both casual/formal speech and formally with calendars and such, saturday and sunday are always put at the end.
The names being numerical was because that's how the names were named during Holy Week (the week that ends with easter sunday), christians were supposed to rest and not work during that week, so sunday was the first rest day, monday the second rest day, etc. which is what the names mean, some people today think it means fair as in state fair/market, e.g. monday is "segunda-feira" = "second fair", but it actually means something closer to holiday, the modern portuguese word being férias.
The reason it took over was basically because the church said so, the old names were still based on old gods and the new nomenclature was adopted for all weeks instead of being Holy Week exclusive.
I guess if the aliens landed in portugal that would be another thing to add to the thread :)
All Christian denominations agree with the Jewish ones: God rested on the seventh day - The Sabbath, or Saturday. Jesus was then resurrected on the day after the Sabbath, the first day of the Jewish week, which became the Lord's Day in many European languages (Domenica, Domingo, Duminică etc). It was quickly understood as a non-working day, a day of religious celebration, but it was still the first day of the week.
Now, since Jesus and his resurrection are much more important in Christianity than the creation of the world, the Sabbath began losing its importance, and so renumbering the week started making sense, but was a contentious religious and political issue for a long time. Of course, having two rest days, and one of them being based on Jewish customs in a quite anti-semitic medieval Europe, played a part as well in wanting to change things.
I'm relatively sure that the Portuguese week day names are based on the original Jewish week.
