The week in the hobbits' calendar was taken from that of the Dúnedain. Its day-names were translations of names given by the Dúnedain following the Eldar. The six days of the Eldar already had days dedicated to the Sun, Moon, Stars, the two trees of Valinor, the Sky, and the Valar, in that order.
Origins[]
The Dúnedain kept the dedications and order, but altered the fourth day, originally called "Tree-day" in reference to the eldest tree of which a descendant grew in Númenor, and, desiring a seventh day week and being great mariners, added a Sea-day after the sky day.
Days[]
The hobbits also took over this arrangement, but the meanings of the days were soon forgotten, and then reduced in form. The 'translation' was made more than a thousand years before Bilbo's time. In the oldest records in the shire in the earliest parts of the great writ of Tuckborough, the names appeared in the archaic forms.
