Samhain - the end? of Summer - is a point at the passing of summer to
winter. In the calendar, this can be pegged at the evening of GIAMONIOS
Day 1, the cusp of summer/winter. The 'trenae' are 3-day festivals before
and after Samhain, and as such are the days marked as IVOS (feast)
before and after GIAM 1, the last 3 days of CUTIOS and the first 3 days of
As for TRINUX SAMONI SINDIU (IVOS), this has a functional meaning of
this day's notations originated in a swap with DAY 3 upper fortnight of
SAMONIOS and 'this day is a feast'. Despite the fact that linguistically its
not exactly clear how this is derived linguistically, it still *means* that.
This doesn't just happen on the TRINUX day, there are 56x5=280 swapped
days on the calendar, plus 144 dragged days after the intercalaries, thats a
total of 424 days which provide the information about their originating
day. This isn't up for grabs, its the simple basic way the experts in the
patterns of the calendar have been showing it works for over a century
now. Its utterly basic to the way the calendar works.
