In the seventh month, in the first day of the month, shall you have a sabbath, a memorial of blowing of trumpets, an holy convocation (
Leviticus 23:24).
Jewish months are set by observing the new moon. In 2017, Trumpets was the 1st of
Tishri (September 21-22). The moon was sighted over Israel but the Sanhedrin need enough time to find two acceptable witnesses and light signal fires across Israel to notify the people. See
Trumpets. Trumpets was not September 20-21 based on the perpetual calendar of Hillel II and not September 22-23, the day of the Revelation 12 sign. Since the cross occurred in 27-33 AD, we are ~1990 years from the cross and ~5990 years from creation. Therefore, the event of the Rapture could occur in the next few years. The Revelation 12 sign occurred before the Rapture.
You are all the children of light, and the children of the day: we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober. For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, Who died for us, that, whether we wake or sleep, we should live together with him (
1 Thessalonians 5:5-6, 9-10).
Yom Teruah is the right day but 2017 is not the right year.
