New Reckoning
The New Reckoning was the calendar system established in the Reunited Kingdom of Gondor and Arnor after the final defeat of Sauron. It marked a deliberate return to the ancient Kings' Reckoning of Númenórean origin, but adapted to begin the year in spring, following the Eldarin loa or 'growth' year rather than the midwinter start used by the Dúnedain in the Third Age. The first year of the New Reckoning began on March 25, 3019 of the Third Age, the very day on which the One Ring was cast into the Cracks of Doom and Barad-dûr fell. This date was chosen to commemorate the Ring-bearers' deed and the overthrow of Sauron, and it became the fixed point from which all subsequent years were counted in the King's domains.
Structure and Festivals
The New Reckoning retained the twelve months of thirty days each from the Kings' Reckoning, but inserted three Enderi or 'Middle-days' between the months of Yavannië (September) and Narquelië (October), corresponding to September 23, 24, and 25 old style. The second of these Middle-days was called Loëndë, the Mid-year's Day. In honor of Frodo Baggins, Yavannië 30—which corresponded to the former September 22, Frodo's birthday—was made a festival called Cormarë or Ringday. In leap years, this feast was doubled to provide the extra day, rather than adding an Overlithe as in the Shire calendar. The year thus maintained a length of 365 days, with the leap-year adjustment built into the celebration of the Ring-bearer.
Adoption and the Shire
The New Reckoning was adopted throughout all lands under the rule of King Elessar, except the Shire. The Hobbits of the Shire retained their own Shire Reckoning, which had begun with the crossing of the Brandywine in Year 1 of the Shire (Third Age 1601). In the Shire, the Fourth Age was held to have begun with 2 Yule 1422, not with the previous March. The Hobbits did not commemorate March 25 or September 22 as official holidays, though in the Westfarthing a custom grew of making holiday and dancing in the Party Field on April 6, which some associated with Samwise Gamgee's birthday, others with the first flowering of the Golden Tree in 1420, and still others with the Elves' New Year. In Buckland, the Horn of the Mark was blown at sundown every November 2, followed by bonfires and feasting.
Chronological Significance
The New Reckoning was not merely a practical calendar reform; it was a symbolic act of restoration and commemoration. By anchoring the year to the date of Sauron's overthrow and honoring Frodo with a festival, the Reunited Kingdom wove the memory of the War of the Ring into the very fabric of time. The Fourth Age itself was officially considered to have begun with the departure of Master Elrond from Middle-earth in September 3021, but for record-keeping in the Kingdom, Fourth Age 1 was the year that began according to the New Reckoning on March 25, 3021 old style. This dual system—the New Reckoning for the King's realm and the Shire Reckoning for the Hobbits—reflected the broader political and cultural settlement after the war, in which the Shire retained its autonomy while acknowledging the authority of the restored King.
