In the ancient world there were several different systems of numbering days of the week, among which there was an “astrological week”, the establishment of which was attributed to Pythagoras, and according to which Sunday was the fourth day, as the orbit of the Sun, the luminary associated with Sunday SVG, according to the Pythagoreans, took fourth place in the distance from the Earth, which in turn was considered the center of the universe, according to the scheme: Saturn-Jupiter-Mars-Sun Venus-Mercury-Man-Moon. Another was the numbering of days in the so-called “planetary week”: Sunday was the second day there.

Nowadays, Sunday is considered the last day of the week in Europe. According to the international standard ISO 8601, the first day of the week is Monday, and Sunday is the last day of the week.
