Tue

Tue is an abbreviation used in English to denote Tuesday. It appears on calendars, schedules, timetables, and in informal writing. Depending on the style guide, it may be written as Tue with no period, or as Tue. with a trailing period. In many digital interfaces and English-language interfaces, Tue is the common three-letter day name.

Etymology and form: The English name Tuesday derives from the Old English Tiwesdæg, meaning Tiw’s Day, named after the god Tiw (Tyr). The abbreviation Tue reflects the first three letters of Tuesday in English. In other languages, weekday abbreviations differ, but many follow a similar practice of shortening the day’s name.

Usage and context: Tue is standard in calendars, scheduling software, and everyday shorthand. In formal prose, some style guides prefer spelling the day in full (Tuesday) or using the period form (Tue.). All-caps forms (TUE) are common in headings or tables. The choice of capitalization and punctuation varies by locale and context.

Calendar conventions: In systems that follow ISO 8601, the week starts on Monday, making Tuesday the second day of the week. In calendars that begin the week on Sunday, Tuesday is the third day. This affects how weekday numbers are presented alongside Tue in different software and documents.
