While Rome's past abuses did bear striking similitude with the Biblical portrait of the Antichrist and the Great Whore, and thus earned it a vigorous plastering of damning reproaches that continue even to this very day, Rome does not have its root in Ishmael, does not have the power to erect a global empire, and is not capable of rising to prominence as a dictatorial state with global reach.
The greatest danger represented by the Roman church today is that it has become so saturated with mealy-mouthed leftist mush-mindedness that it just might self-align with a rising Islamist Antichrist out of sheer leftist, touchy-feely, multi-culturalist stupidity, and so be caught in a position that forces a choice between a revival of 14th century antagonism toward actual followers of Jesus Christ and organizational survival; to wit "Live dead, or die alive."
In that condition, however, I wot that no true followers of Christ presently keeping faith within Catholic churches throughout the world would long remain there, but would break fellowship, even to the point of tearing away entire congregations to follow after Christ rather than Rome. Such a break would — quite literally — suck the life out of the Roman church, and leave behind nothing more than an empty, and impotent shell incapable of anything beyond political posturing, and the promulgation of vapid opinions.
It remains to be seen whether Rome will take that track, or be emphatically, unshakably aligned with her risen LORD in the growing global revival. I pray that we see the latter.
In the book of the prophet Daniel, this false prophet is described as a king (the eleventh horn on a terrible beast) who would wage war against the Jews and would change the Law — including the calendar and the holidays (Daniel 7:8, 25).
Daniel 7
(8) I considered the horns, and, behold, there came up among them another horn, a little one, before which three of the first horns were plucked up by the roots; and, behold, in this horn were eyes like the eyes of a man, and a mouth speaking great things.
(25) And he shall speak words against the Most High, and shall wear out the saints of the Most High; and he shall think to change the seasons and the law; and they shall be given into his hand until a time and times and half a time.
Changing the Sabbath to Sun-day, in honor of the 'venerable day of the sun', changes YHWH's Law regarding the 4th Commandment. The papacy changed all that with their revision of the Julian calendar, which became the Gregorian calendar. Under the Gregorian calendar, the New Year is changed and is no longer in the spring as God commanded. (Changed the season) Passover was changed to Easter and of course the Sabbath was changed to SUN day. That, along with starting the "day" at midnight, made their "change of times and seasons" complete.
Let all judges and all city people and all tradesmen rest upon the venerable day of the sun. But let those dwelling in the country freely and with full liberty attend to the culture of their field; since it frequently happens that no other day is so fit for the sowing of grain or the planting of vines; hence, the favorable time should not be allowed to pass, lest the provisions of heaven be lost. Quoted in Blakely, p. 269
On the venerable Day of the Sun let the magistrates and people residing in cities rest, and let all workshops be closed. In the country, however, persons engaged in agriculture may freely and lawfully continue their pursuits; because it often happens that another day is not so suitable for grain-sowing or for vine-planting; lest by neglecting the proper moment for such operations the bounty of heaven should be lost.

For the Jews the 1st month is Nissan, (March/April-[spring]) and its Gregorian equivalent is January (winter). The Jewish calendar has certainly had no effect on their Sabbath. Unlike the changes via papal bulls, and decrees of Constanine and Pope Gregory where we get a change not only in when the New Year was to begin, but a change of the 4th Commandment. Not to mention the disappearance of Passover and the adoption of Astarte/Ishtar (Easter), a pagan holiday named for the pagan godess well known at the time.
The Gregorian Calendar is a revision of the Julian Calendar which was instituted in a papal bull by Pope Gregory XIII in 1582. The reason for the calendar change was to correct for drift in the dates of signifigant religious observations, (primarily Easter/Astarte/Ishtar) and to prevent further drift in the dates.
The important effects of the change were:
Adoption of the new calendar was essentially immediate within Catholic countries. In the Protestant countries, where papal authority was neither recognized nor appreciated, adoption came more slowly. More information on the Gregorian calendar.
Exodus 12
1 And YHWH spoke unto Moses and Aaron in the land of Egypt, saying:
2 'This month shall be unto you the beginning of months; it shall be the first month of the year to you.
This was commanded by YHWH to Moses at the time of the Passover, which always comes in spring.
In accordance with its ancient beginnings (right from The Seven Days Of Creation when light was created after the darkness), Bible calendar days were, and are, determined to begin and end at sunset e.g "from evening to evening shall you keep your sabbath" (Leviticus 23:32 )
Genesis 1
5 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
Leviticus 23
32 It shall be unto you a sabbath of rest, and ye shall afflict your souls: in the ninth day of the month at even, from even unto even, shall ye celebrate your sabbath.
