Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

bĭnoctĭum, ii, n. [bis-nox], a period or space of two nights, two nights (post-Aug and rare; perh. only in the two foll. exs.), * Tac. A. 3, 71: biduum et binoctium, Amm. 30, 1, 8.
