It seems that the timeline of 2010-2017 as below is the most reasonable and popular one.
The beginning of the Tribulation : Nov.6-8,2010
The mid point : Passover week, 2014
The returning day of Yeshua : Rosh Hashanah or Yom Kippur, 2017
However, a problem of this schedule is what happens with the prophecy of Yeshua which is written in Matthew 24:22.
"And except those days should be shortened, there should be no flesh be saved:
but for the elect's sake those days shall be shortened."
This prophecy of God the Son can't be just ignored or omitted without fulfilling.
And this prophecy can't be fulfilled at the end of 7 years, because Yeshua must return on the day of Rosh Hashanah or
Yom Kippur, 2017.
It can't be fulfilled at the end of the first 3.5 years as well, because the abomination of desolation in the Holy place must
happen during Passover week in 2014.
The only way I can think of how this prophecy can be fulfilled is like this.
Let's suppose the shortened days are 30-50 days, and the beginning of the Tribulation will be delayed for this length from
Nov.6-8 of 2010, then the same length will be shortened at the end of the first 3.5 years so that the abomination of desolation
in the Holy place will be occurred during Passover week in 2014.
This way, some events which suppose to happen before the departure could be fulfilled too.
This is why I believe the unprecedented Anointing of fire and glory will come very shortly so that a great number of the new Bride
(hopefully a million) could be added to the marriage supper of the Lamb.
