Hello and well-met, fellow traveler, and happy Durin's Day!
I predict that Friday, the fourteenth of December, is the first day of the dwarves' new year ~ being the first day of the last moon in Autumn, just before winter. Dwarves call their new year's day, "Durin's Day" if the sun and moon are in the sky together. By happy circumstance, the moon will rise on Friday around 8:30 in the morning, and not set until after dark - nearly 7:00 in the evening!
Huzzah, hooray! Ring in the (dwarves') new year!
