The 2023 Finnish parliamentary election is held, with the centre-right National Coalition led by Petteri Orpo receiving the most votes. [93] IIXX was how people associated with the XXII Roman Legion used to write their number. The practice may have been due to a common way to say "twenty-second" in Latin, namely duo et vice(n)sima (literally "two and twentieth") rather than the "regular" vice(n)sima secunda (twenty second). [35] Apparently, at least one ancient stonecutter mistakenly thought that the IIXX of "22nd Legion" stood for 18, and "corrected" it to XVIII. [35] May 9 – Cyclone Mocha forms in the Indian Ocean, killing over 400 people and injuring over 700 as it strikes Myanmar and Bangladesh. [122] The Roman numerals, in particular, are directly derived from the Etruscan number symbols: ⟨𐌠⟩, ⟨𐌡⟩, ⟨𐌢⟩, ⟨𐌣⟩, and ⟨𐌟⟩ for 1, 5, 10, 50, and 100 (they had more symbols for larger numbers, but it is unknown which symbol represents which number). As in the basic Roman system, the Etruscans wrote the symbols that added to the desired number, from higher to lower value. Thus, the number 87, for example, would be written 50 + 10 + 10 + 10 + 5 + 1 + 1 = 𐌣𐌢𐌢𐌢𐌡𐌠𐌠 (this would appear as 𐌠𐌠𐌡𐌢𐌢𐌢𐌣 since Etruscan was written from right to left.) [58] September 2 – The Indian Space Research Organisation (ISRO) successfully launches Aditya-L1, India's first solar observation mission. [202]

January 18 – A helicopter crash in Brovary near Kyiv, Ukraine kills 14 people including Ukrainian Minister of Internal Affairs Denys Monastyrsky. [17] [18] [19] So why go to all the time and expense of re-recording those three classics thirty plus years later? March 2 – The National Assembly of Vietnam declares Võ Văn Thưởng as the country's new president after receiving 98.38% votes from the Vietnamese parliament. [62] January 3 – Starting from this date, many countries impose travel restrictions on travel from China due to the relaxation of the country's zero-COVID policy. [4]Boethius (1867) [6th century AD].

Roman numerals are sometimes used to represent the days of the week in hours-of-operation signs displayed in windows or on doors of businesses, [72] and also sometimes in railway and bus timetables. Monday, taken as the first day of the week, is represented by I. Sunday is represented by VII. The hours of operation signs are tables composed of two columns where the left column is the day of the week in Roman numerals and the right column is a range of hours of operation from starting time to closing time. In the example case (left), the business opens from 10 AM to 7 PM on weekdays, 10 AM to 5 PM on Saturdays and is closed on Sundays. Note that the listing uses 24-hour time. Rome was founded sometime between 850 and 750 BC. At the time, the region was inhabited by diverse populations of which the Etruscans were the most advanced. The ancient Romans themselves admitted that the basis of much of their civilization was Etruscan. Rome itself was located next to the southern edge of the Etruscan domain, which covered a large part of north-central Italy. Selanjutnya kita ubah angka tersebut sesuai dengan simbol huruf romawi yang mewakili nilainya serta menggabungkannya, sehingga dinyatakan dengan 2023 = 1000 + 1000 + 10 + 10 + 1 + 1 + 1 = M + M + X + X + I + I + I = MMXXIII.

Dalam bentuk simbol angka romawi dinyatakan dengan MMXXIII = M ditambah M ditambah X ditambah X ditambah I ditambah I ditambah I : June 20 – At least 46 people are killed after a riot between MS-13 and Barrio 18 gang members at a women's prison near Tegucigalpa, Honduras.

June 13 – At least 106 people are killed when a wedding boat capsizes on the Niger River in Kwara State, Nigeria. [147]It was a common alternative to the apostrophic ↀ during the Imperial era around the Roman world (M for '1000' was not in use until the Medieval period). [50] [51] It continued in use in the Middle Ages, though it became known more commonly as titulus, [52] and it appears in modern editions of classical and medieval Latin texts. [53] [54] February 16 – Lawmakers in the Russian State Duma vote to withdraw Russia from 21 conventions of the Council of Europe. [52] There are also historical examples of other additive and multiplicative forms, and forms which seem to reflect spoken phrases. Some of these variants may have been regarded as errors even by contemporaries. In education, school grades (in the sense of year-groups rather than test scores) are sometimes referred to by a Roman numeral; for example, "grade IX" is sometimes seen for "grade 9".
