Which would seem to link up with the “taken by the fairies” aspects in the old stories. (Supposing of course this term is related to the Tuatha na Danaan(sp?))
Turn yourself around.
That’s what it’s all about.
Nope. As the clock sits on my north wall or lays on the floor the hands turn east at the top of the cycle. As it sits on my southern wall or is nailed to the ceiling the hands turn west at the top of the cycle.
Sundial shadows turn clockwise in the northern hemisphere. That’s the whole story.
What they called it before is anyone’s guess, I think.
No, no, no. The etiquette is pass the dutchie on the left-hand side. Hehe. 
“Deosil” and “deasil” do not obey the rules of spelling in Scottish. According to my Gaelic dictionary, the word is deiseal which translates as southward, lucky, ready, or turning from east to west in the direction of the sun.
Tuathal is the correct spelling and translates as contrary to the course of the sun.
I am not able to find Danaan or any similar word in the dictionary.
Hope this helps.
Well, you won’t, because it isn’t a “word” per se. It’s the genitive form of the name Dana or Danu, an ancient Celtic goddess. Tuatha means “tribe” and would seem to be unrelated, or only coincidentally related, to tuathal meaning “towards the left”.
I don’t know the origin of withershins but I don’t think it comes from any Gaelic language.
“Dextral” means clockwise and “sinestral” means counterclockwise - but I don’t know if the terms are older than clocks. They derive from the Latin “dexter” = right and “sinister” = left. They are used, for example, to describe the helices in sea shells. The numeral 6 is a dextral spiral and the Greek rho is a sinestral spiral.
This is from memory - forgive any spelling errors or, heaven forbid, confusion.
