It seems clear that the Eldar in Middle-Earth, who have, as Samwise remarked, more time at their disposal, reckoned in long periods, and the Quenya word "yén", often translated "year" (I, 394), really means 144 of our years. The Eldar preferred to reckon in sixes and twelves as far as possible. A "day" of the sun they called ré and reckoned from sunset to sunset. The yén contained 52,596 days. For ritual rather than practical purposes the Eldar observed a week or enquië of six days; and the yén contained 8,766 of these enquier, reckoned continuously throughout the period.

It sounded sheer nonsense. Graham snatched at the last phrase with an unsteady mind. "Sixdoz lions?" he said.
"Didn't you have lions? I suppose not. You had the old pounds? They are our monetary units."
"But what was that you said - sixdoz? "
"Yes. Six dozen, Sire. Of course things, even these little things, have altered. You lived in the days of the decimal system, the Arab system - tens, and little hundreds and thousands. We have eleven numerals now. We have single figures for both ten and eleven, two figures for a dozen, and a dozen dozen makes a gross, a great hundred, you know, a dozen gross a dozand, and a dozand dozand a myriad. Very simple?"
