Overview

Tuesday is the day that falls between Monday and Wednesday. Depending on how a calendar week is numbered, Tuesday can be the second day (ISO 8601 standard, where Monday is first) or the third day (in systems that begin the week on Sunday, as is common in the United States). In everyday life it is typically an ordinary workday in most countries.

Name and linguistic origins

The English name "Tuesday" comes from an Old English dedication to the god Tiw (also Tyr in Norse tradition). In many Romance languages the weekday derives from the Roman god of war—Mars—producing names such as Spanish "martes" and French "mardi". These parallel naming patterns reflect how different cultures mapped their own deities or planets to the seven-day cycle.

History and calendar position

Modern calendars and international standards affect how Tuesday is numbered: under ISO rules it is day two of the week, while other conventions treat it as the third day. Historical practices, religious observances and civic schedules have also shaped Tuesday’s role: for example, in some countries important civic events and local markets have traditionally been held on Tuesdays.

Cultural notes and uses

Several notable customs and phrases highlight Tuesday’s place in culture. In many Christian traditions the day before Ash Wednesday is celebrated as "Fat Tuesday" or "Mardi Gras," a period of feasting. In the United States, the long-standing tradition places many elections on a Tuesday in November. Some national and regional calendars assign colors or other symbolic associations to weekdays, so the cultural meaning of Tuesday can vary widely.
