Roman numerals Numbers in the Roman numeral system

The numeric system represented by Roman numerals originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers in this system are represented by combinations of letters from the Latin alphabet. Roman numerals, as used today, employ seven symbols, each with a fixed integer value, as follows:

A common year starting on Saturday is any non-leap year that begins on Saturday, 1 January, and ends on Saturday, 31 December. Its dominical letter hence is B. The most recent year of such kind was 2011 and the next one will be 2022 in the Gregorian calendar or, likewise, 2017 and 2023 in the obsolete Julian calendar, see below for more. Any common year that starts on Wednesday, Friday or Saturday has only one Friday the 13th; The only Friday the 13th in this common year occurs in May. Leap years starting on Friday share this characteristic.

The Julian calendar, proposed by Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on 1 January 45 BC, by edict. It was the predominant calendar in the Roman world, most of Europe, and in European settlements in the Americas and elsewhere, until it was refined and gradually replaced by the Gregorian calendar, promulgated in 1582 by Pope Gregory XIII.

The Bulgars were Turkic semi-nomadic warrior tribes that flourished in the Pontic-Caspian steppe and the Volga region during the 7th century. Emerging as nomadic equestrians in the Volga-Ural region, according to some researchers their roots can be traced to Central Asia. During their westward migration across the Eurasian steppe the Bulgars absorbed other ethnic groups and cultural influences, including Hunnic and Indo-European peoples. Modern genetic research on Central Asian Turkic people and ethnic groups related to the Bulgars points to an affiliation with Western Eurasian populations. The Bulgars spoke a Turkic language, i.e. Bulgar language of Oghuric branch. They preserved the military titles, organization and customs of Eurasian steppes, as well as pagan shamanism and belief in the sky deity Tangra.
