At midnight on New Year's Eve sixteen bells would be struck - eight bells for the old year and eight bells for the new.
Most of the crew of a ship would be divided up into between two and four groups called watches. Each watch would take its turn with the essential activities of manning the helm, navigating, trimming sails, and keeping a lookout.
The hours between 16:00 and 20:00 are so arranged because that watch (the 'dog watch') was divided into two. The odd number of watches aimed to give each man a different watch each day. It also allows the entire crew of a vessel to eat an evening meal, the normal time being at 1700 with First Dog watchmen eating at 1800.
