There are fifteen inhabited islands in the Outer Hebrides also known as the Western Isles (Scottish Gaelic: Na h-Eileanan Siar), off the west coast of mainland Scotland. Most celebtared the New Year on January 1st, except for one. Berneray (Scottish Gaelic: Beàrnaraigh na Hearadh) in the Sound of Harris (Caolas na Hearadh), sticks to the tradition of Oidhche Challain, the Old New Year, which is celebrated on January 12th. This is in line with the former Highland tradition of following the Julian Calendar, which was subsequently replaced by the Gregorian calendar.
