Yes Gary, the Lord does want us to know all things. You mention many dates from the prophet Daniel concerning the 1260, 1290, 1335 days. When these times are unsealed the end will come according to scripture.

     First must come the knowledge of the Day of the Lord. This day is both terrible and glorius. And we know according to 2 Thess 2 that this is when we assemble to meet the Lord. Also this Day cannot come till the antichrist takes his seat in the temple of God. Day of the Lord for the righteous glorius but brings the bowl judgements upon the wicked.

     Because I would have to write a book to explain every detail I am going to say the Day of the Lord happens on Pentecost. This is why Peter and the Spirit chose this scripture (Acts 2:20 ) to include the Day of the Lord on Pentecost. Birthday of the church started here , it will also end here for many more reasons.

The antichrist takes his seat at 1260 days, 30 days later at 1290 days the abomination of desolation is placed, then at 1335 days is the Blessed Day mentioned in Dan 12, which is also the Day of the Lord. To make things complete for knowledge of when things begin substract 1335 days from the future Pentecost 3 1/2 years in the future. The date will almost always come up mid-October. So I would look for the Tribulation to begin in October.

     This is a prime year for me considering history says King Herod died in 4 BC and the Lord was born about 5 BC, Add one more year for no ( 0 ) year, we deduct 6 years to correct the calendar making it year 27 AD. Deduct another 7 years and we are at year 2020. So if history is correct get ready saints.   Ernie
