Revelation Chapter 12 is often called the most important chapter in the Bible. I totally agree with that statement. Chapters 11 and 12 are the only two places in the entire Bible where the number 1260 can be found. Unfortunately many people believe this number is the same number of days associated with the 42 months mentioned in chapter 11 or with a time, times, and half a time mentioned in verse fourteen. These people believe this lie because they think God uses a thirty day monthly calendar based on a 360 day year, a lie from the pit of hell. In chapter 11 the number is associated with the length of the ministry of the two end-time witnesses. The two witnesses prophesy for 1,260 days clothed in sackcloth. At the end of their ministry the beast that ascends from the bottomless pit will make war against them and overcome and kill them. These two witnesses have been alive for over two thousand years and they were actual eye-witnesses to the ministry of the Lord Jesus, the very reason they are called the two witnesses. I see their ministry begin either in 2023 or 2027. If their ministry begins in the autumn of 2023 on Monday Elul 27 then it will end exactly 1260 days later on 'The Feast of Firstfruits' when Jesus resurrected from death (Nisan 16, Feb. 21st in 2027). If however they begin to minister in 2027 it will be exactly 2,000 Hebrew calendar years and a mirror image of the Hebrew calendar fulfillment of the Lord Jesus 1,260 day ministry. Their ministry will begin exactly two thousand Hebrew calendar years from the exact same day Jesus began his ministry. These two men will likely begin to minister on Monday Elul 27 in 2027 AD (Sept. 26th) and finish on day 1260 when they are killed by the beast from the bottomless pit. They will be mocked for 3.5 days as the world celebrates until the spirit of life from God enters them and they stand upon their feet (Mar. 13th in 2031 AD, Nisan 21). Then they will hear a great voice from heaven saying, come up hither, and they will ascended unto heaven in a cloud and their enemies will behold them.
In Revelation chapter 12 the woman clothed with the sun with the moon under her feet bore a male child who was to rule all nations with a rod of iron. This is undoubtedly a reference to the Lord and Messiah Jesus Christ. One important reason to understand the significance of the 1260 days is simply because this was the exact length of Jesus ministry from the day of His baptism in the Jordan River(when He was caught up to the throne of God, Revelation 12:5) until the day of His resurrection on Nisan 16 (Feast of First-fruits) in 31 AD. If this was the exact length of the Lord's ministry then we should be able to plug this value into a correctly interpolated Hebrew calendar simulating the arrival of Messiah as expressed in Daniel's 70-weeks prophecy. Unfortunately there are no known ancient Hebrew calendars available from that exact period. However we do live in the information age and to build a Hebrew calendar based on the known Luna & solar cycles is simply a matter of understanding how to write such a program (The new Elijah calendar is coming soon). It is also known the Hebrews adopted the Babylonian calendar names after they returned to Judah following 70 years of exile. According to Daniel's seventy-weeks prophecy the Messiah was to appear 483 years (solar) from the decree sent forth by King Artaxerxes in 457 BC, but then he was cut off in the middle of the week (the final seven years of the 490 Hebrew calendar years). According to the gospel of John, the Messiah Jesus was baptised four days before he attended a wedding in Cana in Galilee. By using the new Elijah calendar (coming soon) one can use these vital clues to discern the exact start day of Messiah's ministry and then input the 1260 days into the calendar. By doing this correctly the results show that Jesus was baptised four days before the Feast of Trumpets in 27 AD and He worked his first miricle on the Feast of Trumpets when He and His disciple attended the wedding in Cana in Galilee. It was necessary for Jesus to begin his ministry before the Feast of Trumpets because this was the official starting day when all the Kings of Judah began to reign. These same results can be achieved on the current elijah calendar however the set leap months have not been placed in the correct leap year so the results will show only the correct Gregorian calendar date but sometimes the corresponding Hebrew calendar date will be incorrect. Nevertheless one can still see that although the Hebrew month might be wrong it's day of the month is correct. So therefore it becomes a matter of aligning the leap months with the correct leap years. The starting point for King Artaxerxes first decree (solar) began on the Feast of Trumpets in 457 BC. Measuring 483 tropical years foward brings the calculation to about the tenth hour of the day on Elul 27 when Jesus was baptised in the Jordan River by John the Baptist. The day of Jesus baptism would be considered his first day of ministry however when doing these calculations one must start his first day from sunset on the previous day (when the Hebrew day began). On the current Elijah calendar adding 1260 days to the beginning of Elul 27 in 27 AD brings the calculation to Adar 17 (Feb. 23 in 31 AD), only a few minutes into the 17th Hebrew day. However on the new Elijah calendar this calculation will read Nisan 17, the correct Hebrew month and day when Jesus appeared to the disciples in the locked room on the eve of Nisan 16 after his resurrection and the 17th day was beginning. Daniel 9:26 tells us Messiah would be cut off after three score and two weeks or sixty two weeks. This is the same measure of time that follwed the first seven weeks giving a total of 69 weeks of years or 483 years. The two decrees sent by King Artaxerxes are the two determing factors for the starting points; first the solar decree went forth at the Feast of Trumpets in 457 BC and next Nehemiah departed Jerusalem on the 24th day of Nisan in 445 BC. Nehemiah's departure date was exactly 91 Hebrew calendar years from the 24th day of Nisan in 536 BC when Daniel had his chapter 10 vision of the pre-incarnate vision of Jesus (the man in linen). Measuring 483 Luna years from Nisan 24 in 445 BC brings the calculation to Feburary 28 in 31 AD. This day was the 21st day of the month Adar in the current Elijah calendar but in the new Elijah calendar it will be Nisan 21, the last day of the Feast of Unleavened Bread. It was on Nisan 21 that Jesus commissioned the church from the mountain he met them at in Galilee.
Between the two measures of time mentioned in chpater twelve (1260 days and 1278 solar days or a time,times, and half a time) John heard a loud voice in heaven declare "Now is come salvation and strength , and the kingdom of our God, and the power of His Christ: for the accuser of out brethren is cast down, which accused them before our God day and night. Notice that it was Michael the great angel that fought against the dragon when the dragon was cast out from heaven with one third of the angels. This is important because we also recall the statement Jesus made upon the return of the seventy disciples, Jesus said "I beheld Satan as lightening fall from heaven." Undoubtedly this war in heaven transpired while the 'Lord of Host', Jesus, was ministering here on planet Earth.
