Is 0 does a recess appointment how long does it last and is there anything the Senate can do about it and when

[Alas Babylon!]

The President shall have Power to fill up all Vacancies that may happen during the Recess of the Senate, by granting Commissions which shall expire at the End of their next Session.

The next session will start on January 3rd, 2017.

Given that, I don't think they're in recess in at all when one Congress ends and then another begins.

114th United States Congress

Mitch McConnell was officially elected Senate Majority Leader on January 3rd, 2015. So the NEW Senate started business on that day.
