Saturday (from IOM. שבת Shabbat - the day of the week between Friday and voskresenyam traditions inherited from Judaism, Saturday is the last day of the week. This agreement remains the standard in the U.S. and in Israel, but in modern Europe, many people regard the Sabbath as the sixth (last but one) day of the week, and Sunday as the last. Modern European understanding embodied in ISO 8601. In a secular tradition, Saturday Slavs also called the last (the sixth day).[3]
Countries with strong Christian traditions continue to regard the Sabbath as the seventh day of the week. This correlates with the late ancient tradition, in which days of the week was associated with a family of classical planets (the Sun[4], the Moon, Mars, mercury, Jupiter, Venus, Saturn), and the first day of the week was dedicated to the Sun as the most important luminary, other days were devoted to the luminaries in descending order according to their size in the view of the ancients.
