Here it is an hour and a half approximately after Jun-san's post
and noone has come up with an answer on formal practice on
New Year's Eve or New Year's Day.
Sorry about that, I wasn't aware I was on the clock.
We have misogi. 108 shomenuchi ikkyo suwari waza, giving and receiving, with one partner, and then four each with everyone else in the dojo. Then we have a party.
