European Calendar? In the United States, many Christians say that they observe Sunday, the first day of the week, at least in part, to commemorate the resurrection which they believe took place on the first day of the week. However, many areas of Europe use a calendar that has Sunday as the seventh day of the week. Does anyone know, in those areas that use that calendar, on what day they hold their weekly worship services? If they hold it on the seventh day, do they also do anything special on the first day?
