How Icelandic Day Names Are Formed

Most day names in Icelandic end in -dagur, which means “day” (related to English “day” and German “Tag”). The first part of the word often refers to a Norse god or celestial body. For example:

  • Mánudagur – “Moon Day” (Monday)
  • Þriðjudagur – “Third Day” (Tuesday)
  • Föstudagur – “Fasting Day” (Friday)

Interestingly, miðvikudagur (Wednesday) literally means “mid-week day,” and laugardagur (Saturday) comes from the word for “bath,” reflecting the old tradition of bath day before Sunday rest.

Grammar Tip: Saying “On Monday” in Icelandic

To say “on Monday” or “on Friday,” you typically use the dative case with no preposition. The word mánudagur (nominative) becomes mánudegi (dative). For example:

  • Ég fer í skólann á mánudegi. – “I go to school on Monday.”

Although modern Icelanders often omit á (on), it’s helpful to recognize both forms when reading or listening.
