day time interval

Ἄλλο μέντοι γέ ἐστι μοῖρα καὶ ἄλλο ἡμέρα. Μοῖρα μὲν γάρ ἐστι διάστημά τι λʹὸν μέρος ὑπάρχον τοῦ ζῳδίου, ἡμέρα δέ ἐστι χρόνος λʹὸν μέρος ὡς ἔγγιστα τοῦ μηνιαίου χρόνου. Καὶ ἡ μὲν μοῖρα τξʹον μέρος ἐστὶ τοῦ ζῳδιακοῦ κύκλου, ἡ δὲ ἡμέρα τξεʹον καὶ δʹον μέρος ὡς ἔγγιστα τοῦ ἐνιαυσιαίου χρόνου. Καὶ πάντα μὲν τὰ ζῴδια τριακονταμόριά ἐστιν, οὐ πάντα δὲ τριακονθήμερα.

‘A degree is one thing though and a day another. For a degree is a certain interval, being a 30th part of the zodiac sign, while a day is a time period, as close as possible to a 30th part of the time of a month. Also, the degree is a 360th part of the zodiac, and the day as close as possible to a 365th and a 4th part of the time of a year. Also, all zodiac signs consist of thirty degrees, but not all of thirty days.’
