Coranar

From Tolkien Gateway

Coranar meaning literally "sun-round", a name given by the Elves to a single solar year.[1][2]

The Valar intended a Year of the Sun to be exactly 350 full days, being a 1/10 fraction of a Year of the Trees. However the Sun and Moon were slower than expected in their passage than the Valar had intended, and in one coranar, the Sun turns 365.25 times instead of 350, or approximately 1/9.58 of a Year of the Trees.[3]

Although the Dúnedain (and the Hobbits) divided the coranar in 365 days, the extra hours (5 hours, 48 minutes, 46 seconds) accumulated a deficit after centuries; to remedy this, some calendars included a "leap-year" every four years (see: enderi, Overlithe).

144 coranari made a yén which was the basic unit of time for the immortal Elves.
