What's in the mind of the SO poster?
I love the bridge I'm gonna make! This is a SO post.
There are not any technicalities involved, you can ignore the code of the declare table insert ..... stuff, and just focus on the dates the OP has, and the ones they need.
I though, "who can guess this obscure fact"? And the answer was "Only the crazy geniuses at puzzling!!!"
Can anyone figure the request out?

I know the accepted answer has more detail, but it appears that the first poster was just as correct with determining the request...?

group overlapping events.

F 2018-10-05 03:31:51.000 2018-10-20 22:20:33.000
It you order it chronologically, row F is the first event.
Row E starts at the same time, but ends after, so
we group these two rows:(F) 2018-10-05 03:31:51.000 (E) 2018-10-21 02:12:58.000
Then D starts before E finishes,
so we group again (F) 2018-10-05 03:31:51.000 (D) 2018-10-22 16:10:53.000
Row C event starts after D is finished
but it is overlapped with B (C) 2018-10-27 04:28:16.000 (B) 2018-11-17 17:15:36.000
And finally,
Event in row A does not overlap any other event

The request seems to be: there is a table containing pairs of dates, each describing a time interval. The OP is looking for a query combining overlapping intervals, that would give him the minimal set of time intervals exactly covering the time periods that the initial table was covering.
