I believe they are equivalent - 1,260 days of 30 day months equals 42 months and 3 years and a half. God is revealing His measurement - 30 days.
Hi Marilyn,
What God is revealing is the timeline of events for the 7 year 70th week. The timeline of events for the 7 year 70th week is derived from...
the time expressions + the evolving changes of the little horn person. <<<< I am repeating because it is really key.
The 2 witnesses are in the great trib, for that is when the A/C has the power to kill them eventually. The A/C is not a world leader in the first part of the trib. He only rule for 42 months, 1,260 days, 3 1/2 years, (which I see in your diagram.)
The 2 witnesses toward the end part (last 75 days) of their 1260 days time are in the great tribulation.... because the little horn person will have evolved into the beast, and the great tribulation begins when a statue image of the beast is placed on the temple mount.
Marilyn, Revelation 11 does not use the term the Antichrist, but instead "the beast", the final evolved stage of the little horn person.
After the two witnesses are brought back to life and ascend to heaven - on day 1263.5, the beast will have 42 months (a nominal expression) to reign without the two witnesses around to impede him.
============================================
the evolving changes of the little horn person is.... (this is really critical to realize)
the little horn > becomes the prince who shall come > becomes the Antichrist > becomes the revealed man of sin > becomes the beast

As the beast, he is no longer the Antichrist, the invalid King of Israel coming in his own name. Please look at the evolving changes line above.
He will become the Antichrist, invalid King of Israel, as the 7 years begin. Then in the middle part, around 3 years into it, he goes into the temple, sits, claims to be God - revealing himself as the man of sin.
The Jews at that point will be mortified and will reject him as continuing as their King of Israel - which ends his time as being the Antichrist.
God has him killed for his audacious act, but brings him back to life in disdain for him, and as part of God's plan to deal with Satan, who is the one who will convince the person that he can achieve God-hood.
Brought back to life, he becomes the beast. As the beast, he becomes ruthless, cunning, and totally evil, a tool of Satan - who following the exit of the two witnesses, and the 7th trumpet sounding, will be cast down to earth.
