Book of Enoch 82:4–11

⁴ Blessed are all the righteous, blessed are all those who walk in the way of righteousness and sin not as the sinners, in the reckoning of all their days in which the sun traverses the heaven, entering into and departing from the portals for thirty days with the heads of thousands of the order of the stars, together with the four which are intercalated which divide the four portions of the year, which lead them and enter with them four days. (ENO) ⁵ Owing to them men shall be at fault and not reckon them in the whole reckoning of the year: yea, men shall be at fault, and not recognize them accurately. (ENO) ⁶ For they belong to the reckoning of the year and are truly recorded (thereon) for ever, one in the first portal and one in the third, and one in the fourth and one in the sixth, and the year is completed in three hundred and sixty-four days. (ENO) ⁷ And the account thereof is accurate and the recorded reckoning thereof exact; for the luminaries, and months and festivals, and years and days, has Uriel shown and revealed to me, to whom the Lord of the whole creation of the world hath subjected the host of heaven. (ENO) ⁸ And he has power over night and day in the heaven to cause the light to give light to men—sun, moon, and stars, and all the powers of the heaven which revolve in their circular chariots. (ENO) ⁹ And these are the orders of the stars, which set in their places, and in their seasons and festivals and months. (ENO) ¹⁰ And these are the names of those who lead them, who watch that they enter at their times, in their orders, in their seasons, in their months, in their periods of dominion, and in their positions. (ENO) ¹¹ Their four leaders who divide the four parts of the year enter first; and after them the twelve leaders of the orders who divide the months; and for the three hundred and sixty (days) there are heads over thousands who divide the days; and for the four intercalary days there are the leaders which sunder the four parts of the year. (ENO)
