Yes sir, let me quote two specifics prophecies from the bible that talks about the calendar.
Rome removed 10 days from the calendar so easter can fit into their pagan ways...
And all the days of the commandment will be two and fifty weeks of days, and these will make the entire year complete. Thus it is engraven and ordained on the heavenly tablets. And there is no neglecting this commandment for a single year or from year to year. And command you the children of Yashar'el that they observe the years according to this reckoning three hundred and sixty four days, and these will constitute a complete year, and they will not disturb its time from its days and from its feasts; for everything will fall out in them according to their testimony, and they will not leave out any day nor disturb any feasts.
But if they do neglect and do not observe them according to his commandment, then they will disturb all their seasons and the years will be dislodged from this order, and they will disturb the seasons and the years will be dislodged and they will neglect their ordinances. And all the children of Yashar'el will forget and will not find the path of the years, and will forget the New Moons, and seasons, and Shabbaths and they will go wrong as to all the order of the years. YOVHELIYM (JUBILEES) 6:30-34 את CEPHER
For there will be those who will assuredly make observations of the moon how it disturbs the seasons and comes in from year to year ten days too soon. YOVHELIYM (JUBILEES) 6:36 את CEPHER
Daniel 7 25 He shall speak words against the Most High, and shall wear out the saints of the Most High, and shall think to change the times and the law; and they shall be given into his hand for a time, times, and half a time.
I believe the negroes are the biblical hebrews but that is another topic in itself
Pope gregory removed 10 days from the calendar messed up the seasons for the hebrews and the world started keeping pagan holidays
