The following is the Elven Calendar, or “Loa” with what could be termed as the Solar observations.
Turuhalmë (Elven “LogDrawing”) December 21st
Solvalwaris (Purification, begin Stirring): February 2nd
Yestarë (Elven New Year, begin Spring): March 28th
Nost-na-Lothion (Day of Flowers, begin Summer) May 22nd
Tarnin Austa (Gates of Summer) June 21st
Yavië (begin Elven Autumn) August 2nd
Enderi (Middle Days, begin Fading) September 25-27th (all 3 days)
Improvised by Tië eldaliéva:
Cuiverë Quendiva (First day of Winter/Origins of the Elves) November 21st
Tië eldaliéva improvised the Full Moons too, using the Legendarium as much as possible, and will be in the book when published. We hope to republish Dave’s in-depth Calendar article in the near future! In the meantime, you can find the dates of the Elven Moons by using the Encyclopedia of Arda Interactive Calendar – the months in the Quenya language are termed “Numenorean” so you know which one we use.
P.S. Dave/Aikanar/Eluyon, the author of said Calendar Article can also be found at www.westofwest.org.
