The name in Quenya of the tenth month of the year, according to the Stewards' Reckoning of Gondor, following the harvest feast of Yáviérë, and preceding Hísimë. On a modern calendar, Narquelië ran between 22 September and 21 October. The name Narquelië translates as 'Sun-fading', and relates to the fact that this month marked the end of autumn and the onset of winter. Its equivalent in Sindarin (as usually used by the Dúnedain) was Narbeleth, and the descent into the cold of winter was also marked by its names among Hobbits and northern Men: 'Winterfilth' and 'Wintring'.
Notes

Narbeleth was the Sindarin equivalent of QuenyaNarquelië. As well as being used in the calendars of Men, the same Sindarin word was used by the Elves for the season of autumn. We might naturally assume that the Elves would also have used the Quenya name Narquelië, but in fact this was not the case. In Quenya, autumn was simply Quellë or 'fading' (though the idea of fading is also present within the literal meaning of Narquelië, which means 'fire-fading' or 'Sun-fading').
