mánudagur

Mánudagur is the Icelandic name for Monday. In Icelandic calendars, it is the first day of the standard workweek, and it is commonly used to denote the Monday of a particular week in both spoken and written language.

Mánudagur derives from Old Norse mánudagr, a compound of mánu- meaning “moon” and dagr meaning “day.” The modern form preserves the Moon-day origin and reflects the traditional naming pattern for the days of the week in Icelandic.

In Icelandic, day names often reflect astronomical or ordinal roots. Other days include sunnudagur (Sun-day), þriðjudagur (the third day), miðvikudagur (midweek day), fimmtudagur (the fifth day), föstudagur (fast day), and laugardagur (bath day). Together, these names constitute the seven-day week used in contemporary Icelandic language and culture.
