I think I misunderstood you. I thought you were saying that Passover/Feast of Weeks may mark the timing of His coming based on the OP. To that, I say I don't think so.
However, I do agree that like in the garden all will "fall asleep" while watching/waiting on the Lord. This is mainly based on Jesus's parable in Mark 25 about the wise/foolish virgins. But I always thought that the actual announcement/midnight-shout of the coming Bridegroom was realized by the Abomination of Desolation. Correct me if I'm wrong. But, Jesus made it clear that the famines/wars/unrest/earthquakes were actually to be expected. All His followers were to know and watch for this particular sign. Then upon waking the wise virgins with oil were ready to bear light in the darkness; while the fools awoke lost and seeking. Half were found ready and doing the Lord's work; while half either fell away or never truly loved the Lord. John 14:15-16 refers to those that are His.
15 “If you love Me, you will keep My commandments.
16 I will ask the Father, and He will give you another Helper, so that He may be with you forever;
As you know, the oil in the parable represents the Holy Spirit; the Helper that fuels our faith and acts as the seal of God on believers. He marks us as belonging to Him and no one can take us away from Him. Those with faith in Christ have nothing to fear from the world, from Satan, nor from death. And to the fair-weather "Christians" that don't keep His commandments, He will say depart from me I never knew you. These are also loosely referenced in Daniel 11 when it's mentioned that hypocrites will join the righteous or fall away.
31 Forces from him will arise, desecrate the sanctuary fortress, and do away with the regular sacrifice. And they will set up the abomination of desolation. 32 And by smooth words he will turn to godlessness those who act wickedly toward the covenant, but the people who know their God will be strong and take action. 33 And those who have insight among the people will give understanding to the many; yet they will fall by sword and by flame, by captivity and by plunder for many days. 34 Now when they fall they will be granted a little help, and many will join with them in hypocrisy. 35 And some of those who have insight will fall, to refine, purge, and cleanse them until the end time; because it is still to come at the appointed time.
Satan rising to power/The Great Falling Away/The Great Tribulation MUST come first. Once these are fulfilled and only then does the Lord's coming become imminent and can happen at any time. At that point, no one knows the timing and the anti-christ will further confuse the days and times in some way. Many refer to this as a Pre-Wrath Rapture since Satan's temptation isn't God's Judgement/Wrath. Satan is used merely as a tool to test and refine our faith and trust even to the point of death if needed (much like Christ with God's Will). God has already proclaimed His judgment as cleansing the land by fire along with all His enemies under His feet (on the Earth). To continue with Daniel 12:1-3 we then finally see the redemption of the righteous and Jesus coming with our respective rewards for everyone. Sin's wager is everlasting death, while mercy and everlasting righteousness is rewarded to the saints.
12 “Now at that time Michael, the great prince who stands guard over the sons of your people, will arise. And there will be a time of distress such as never occurred since there was a nation until that time; and at that time your people, everyone who is found written in the book, will be rescued. 2 And many of those who sleep in the dust of the ground will awake, these to everlasting life, but the others to disgrace and everlasting contempt. 3 And those who have insight will shine like the glow of the expanse of heaven, and those who lead the many to righteousness, like the stars forever and ever.
And to wrap up the parable, the closing of the door to the wedding feast is the coming of the Lord on the clouds. Those left behind will find themselves in outer darkness angry that they missed out.
