Kings' Reckoning

The name given to the calendar system used in Númenor, and in Gondor and Arnor during the early part of the Third Age. It divided the year into twelve months (properly called astar), and included three days that did not belong to any month: yestarë, loëndë and mettarë. The King's Reckoning lasted until the loss of Eärnur the last King of Gondor. It was revised by Mardil, the first Ruling Steward, who replaced it with the system known as the Stewards' Reckoning.
