Friday is the sixth day of the week. The name comes from the Anglo-Saxon word Frigedaeg, which means Frigg’s day. Frigg was a goddess of love and marriage in Norse mythology. Frigg was the wife of Odin, the chief Norse god. The Scandinavians considered Friday their luckiest day. But people today associate Friday the 13th with bad luck. One explanation for this belief is that Christ was crucified on Friday, and 13 men were present at the Last Supper. In memory of the Crucifixion, some Christians fast on Fridays, except on a feast day, such as Christmas. Christians observe Good Friday two days before Easter in memory of Christ’s suffering. The Jewish Sabbath begins at sunset on Friday. Friday is also a holy day among Muslims. Muslims also celebrate the creation of Adam on Friday.
