Tisdag

Tisdag is the Swedish name for Tuesday. It is the second day of the week in the international ISO 8601 system, and in Sweden the week typically begins on Monday, placing tisdag after Monday. The name tisdag derives from Old Norse Týsdagr, meaning "Týr's day," with Tyr the Norse god of law and combat. This etymology links tisdag with the English Tuesday, Danish tirsdag, and Norwegian tirsdag, all stemming from the Proto-Germanic root related to the god Tiw/Týr.

Historically, the seven-day week in this form originated in the ancient Near East and was adopted by Germanic-speaking peoples in the early medieval period. The Swedish weekday names reflect this heritage, in contrast to Latin-derived names such as dies Martis used in Romance-language regions.

In modern usage, tisdag is a standard calendar day used in everyday language, education, business, and media. In writing and on calendars it is often abbreviated as tis, or occasionally ti, with the full form tisdag used in more formal contexts. The pronunciation in Swedish is approximately [ˈtiːsˌdɑːɡ].
