Elkanah Day is not listed among the senators in any session in the Civil List of 1858, which means that he did not attend any session, but it is certain that election returns were filed with the Secretary of State of New York in 1780, since he was elected to the Council of Appointment in 1782; the History of Eastern Vermont by Benjamin Homer Hall (Civil list appendix, page 768) lists him as a New York State Senator and stating "Commencement of Session September 10, 1781"
