What calendar did Vikings use? The Vikings had a lunar calendar which means they counted the months from new moon to new moon or full moon to full moon. The word month is actually still referred to as the moon in Scandinavia, which in Danish is called ”måned”.
What did Vikings call the seasons? In Norse mythology, Sumarr (Old Norse: [ˈsumɑrː], “Summer”) and Vetr ([ˈwetz̠], “Winter”) are personified seasons. Sumarr and Vetr, personified, are attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson.
How did Norse count years? The Vikings did not use exact years to date events, a so-called absolute chronology. Instead, they used a relative chronology with reference to the number of years after important events. One could for example date the year by saying “five winters after the Battle of Svolder”.
What did Vikings call months? Each season had 6 months, with 30 days each (lunar phases). Summer months were Harpa, Skerpla, Sólmánuðr, Heyannir, Tvímánuðr and Haustmánuðr, and the winter months Gormánuðr, Ýlir, Mǫrsugr, Þorri, Góa and Einmánuðr. Each month was set to start on a specific weekday in a specific week, and lasted for 30 days.
