fyrradag
Fyrradag is a term originating from Old Norse and is often translated as "first day." Historically, it referred to the first day of the week, which in many pre-Christian Germanic cultures was associated with the sun. This is why the first day of the week is sometimes called "Sunday" in English and similar names in other Germanic languages, such as "Söndag" in Swedish or "Zondag" in Dutch. The concept of a seven-day week itself has ancient roots, with different cultures assigning specific deities or celestial bodies to each day. Fyrradag represents the starting point of this cycle. The specific day designated as "fyrradag" could vary in different regions and time periods. While the modern Christian tradition places Sunday as the first day of the week, the concept of fyrradag predates Christianity and reflects older calendrical systems. The understanding and observation of fyrradag have largely been superseded by modern seven-day week structures and Christian observances, though its etymological connection to the beginning of the week remains.
