Hogmanay is the Scottish New Year celebration held on December 31st, with traditions originating from pagan winter solstice festivals. Some key customs include first-footing, where the first visitor of the new year brings gifts; fireball swinging, where flaming balls are swung on chains; and burning the clavie, a bonfire of casks on January 11th. The celebration continues for several days and involves singing Auld Lang Syne, written by Robert Burns, at midnight to usher in the new year.
