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 is a calendar year with 365 days, as distinguished from a leap year, which has 366. More generally, a common year is one without intercalation. The Gregorian calendar,, employs both common years and leap years to keep the calendar aligned with the tropical year, which does not contain an exact number of days.

A common year starting on Friday is any non-leap year that begins on Friday, 1 January, and ends on Friday, 31 December. Its dominical letter hence is C. The most recent year of such kind was 2010 and the next one will be 2021 in the Gregorian calendar, or, likewise, 2011 and 2022 in the obsolete Julian calendar. The century year, 2100, will also be a common year starting on Friday in the Gregorian 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 August. Leap years starting on Thursday share this characteristic, but also have another one in February.

Glasgow is the most populous city in Scotland, and the third most populous city in the United Kingdom, as of the 2017 estimated city population of 621,020. Historically part of Lanarkshire, the city now forms the Glasgow City council area, one of the 32 council areas of Scotland; the local authority is Glasgow City Council. Glasgow is situated on the River Clyde in the country's West Central Lowlands. Inhabitants of the city are referred to as "Glaswegians" or "Weegies". It is the fourth most visited city in the UK. Glasgow is also known for the Glasgow patter, a distinct dialect of the Scots language that is noted for being difficult to understand by those from outside the city.
A cigarette is a narrow cylinder containing psychoactive material, usually tobacco, that is rolled into thin paper for smoking. Most cigarettes contain a "reconstituted tobacco" product known as "sheet", which consists of "recycled [tobacco] stems, stalks, scraps, collected dust, and floor sweepings", to which are added glue, chemicals and fillers; the product is then sprayed with nicotine that was extracted from the tobacco scraps, and shaped into curls. The cigarette is ignited at one end, causing it to smolder and allowing smoke to be inhaled from the other end, which is held in or to the mouth. Most modern cigarettes are filtered, although this does not make them safer. Cigarette manufacturers have described cigarettes as a drug administration system for the delivery of nicotine in acceptable and attractive form. Cigarettes are addictive and cause cancer, chronic obstructive pulmonary disease, heart disease, and other health problems.
