Some #Gaulish polytheists view #Samonios as equivalent to Irish #Samhain, but this article does a good job explaining how Samhain changed over time and moved much later in the year:

Nonetheless, people may link the two and associate Samonios with November, in which case they'd see the current month as Giamonios — "end of Winter" — and not the start of the New Year.

And even if you follow my reckoning, this would still be the case for the Southern Hemisphere...

Two nights ago was the 1st Quarter Moon 🌓 which would have marked the beginning of the #Gaulish month of #Samonios on the #Coligny calendar — and also the New Year!

Samonios' name clearly refers to the Summer season.

The 2nd day of Samonios' 2nd fortnight (the day after the Last Quarter Moon 🌗) is marked as TRINOSAMO·SINDIV and TRINVXSAMO, taken to mean trínoxtíon Samoní sindíu, "the three nights of Samonios today".
