King’s Reckoning

The calendar of Númenor

Encyclopedia of Arda Timeline
Years of the Trees First Age Second Age Third Age Fourth Age and Beyond

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.



The exact date of origin of the King's Reckoning is not entirely clear, but given that there was no King of Númenor until II 32, we can say for sure that it was not known as the 'King's Reckoning' before that date.


It's stated explicitly that the King's Reckoning was 'ultimately of Eldarin origin' (The Lord of the Rings Appendix D, The Calendars), though we're given no specific detail beyond this. Presumably the calendar would have been adapted from that used by the Elves of Beleriand during the First Age. Known calendars of the Elves, such as the Reckoning of Rivendell, differ from the King's Reckoning in some significant ways, implying that either the Elves used a quite different calendar at that time, or the Dúnedain introduced substantial innovations of their own.
