However, and this is theory of just mine so don't run with this without doing your own study, it's possible that this year is a year of great blessing for Jerusalem. And like you, by "this year" I mean the Jewish year (which started a month ago).
This theory is based on reading Daniel 12 and Revelation 11. Maybe the desecration that causes desolation is building the al-aqse mosque on the Temple Mount (AD 688-ish). 1260 years later is 1948 (Israel restored). 30 years later (Daniel 12:11 says 1290 days or years after desecration) is 1978, the year Israel made peace with Egypt and a time nobody thought was possible. 45 years after that is year AD 2023 (again, in terms of the Jewish calendar that year has already started). Daniel 12:12 is vague (Amplified version): -- How blessed [happy, fortunate, spiritually prosperous] and beloved is he who waits expectantly [enduring without wavering for the period of tribulation] and comes to the 1,335 days!
If I'm right, and that's a big "if", it's not telling us when Christ returns, nor is it telling us the tribulation is beginning. Nor do I believe it's necessarily a global phenomenon. I believe at the narrowest the setting is Jerusalem that's being blessed, or at most the believers of God (Who's temple was in Jerusalem) are being blessed this year. It may be that the 7 years of tribulation are the centuries of horrible persecution of Christians by the Muslims that's been going on in that region, marked by Islam planting their flag on the Temple Mount by building the mosque there 7 centuries ago. (This is based on my theory that us American Christians have a bias in thinking most of the eschatology events have to apply to us or they don't count -- including the horrible persecution that believers have experienced for centuries in that region.)
If 1260 is equivalent to 1948, what year is equivalent to 1335?
1335-1260 = 75
75 + 1945 = 2020
Where did the 45 years after 1978 come from, to arrive at 2023?
