Ἔνην καὶ νέαν

[This] is what Athenians call the day we call the thirtieth, from its being the end of the preceding month and the beginning of the next. But Polemon¹ maintains that once he² called it Demetrias↗ in honor of Demetrius the Macedonian.³ They call "of the day after tomorrow"⁴ and "to the day after tomorrow" the [period] to the third; and by itself e(/non, roughly aspirated, signifies what is prior and past.
