When were the Norse gods worshipped?

The Norse gods were primarily worshipped during the Viking Age, which spanned from around the late 8th century to the early 11th century. Their worship continued to be significant in Scandinavia until the gradual Christianization of the region, which began in the 10th century and continued into the 12th century. Despite the decline in formal worship, Norse mythology and traditions persisted in various forms in folklore and cultural practices long after the official conversion to Christianity.
