It's been 10 days since the President swore in & nominated a Vice President.
Five days since the PPT was confirmed.
Best I can tell, these are the most recent Official Senate Procedures and Rules governing such:
Article 7: Confirmation Hearing
1.) Once a nomination is made by the President, it shall be brought to the floor immediately by the President of the Senate. The President of the Senate shall then open a confirmation hearing for presidential nominees immediately following the president's announcement of the nomination.
2.) Each hearing shall last for at least four days (i.e. 96 hours). The hearing may be abbreviated according to the unanimous consent rules outlined in Article III: Debate.
3.) The vote shall last for a maximum of four days (96 hours). No Senator shall be prohibited from voting until after the nominee has received enough votes to pass or fail confirmation, at which point vote changes shall be prohibited.
