Jub. 6:16 He set His bow in the cloud for a sign of the eternal covenant that there should not again be a flood on the earth to destroy it all the days of the earth. 17 For this reason it is ordained and written on the heavenly tablets, that they should celebrate the "Feast of Weeks" in this month once a year, to renew the covenant every year.

23 And on the new month of the first month, and on the new month of the fourth month, and on the new month of the seventh month, and on the new month of the tenth month are the days of remembrance, and the days of the seasons in the four divisions of the year. These are written and ordained as a testimony forever. 29 And they placed them on the heavenly tablets, each had thirteen weeks; from one to another (passed) their memorial, from the first to the second, and from the second to the third, and from the third to the fourth. 30 And all the days of the commandment will be fifty two weeks of days, and (these will make) the entire year complete. Thus it is engraved and ordained on the heavenly tablets. 31 And there is no neglecting (this commandment) for a single year or from year to year. 32 And command you the children of Israel that they observe the years according to this reckoning- three hundred and sixty-four days, and (these) will constitute a complete year.
