When Does "Harbinger" #1 (1991) Take Place?
"Harbinger" #1 v1 "Children of the Eighth Day" is a superhero comic-book written by Jim Shooter and released October 11th, 1991.
We know this because the issue includes several time and place setting textboxes that range from: "Near the Washington National Airport, District of Columbia. June 2, 1991, 2:35 P.M." on the first page to "Peachtree Place, Atlanta, Georgia, June 6, 11:50 A.M." halfway through the comic. So it's June of 1991.
It takes place on the fictional Valiant Universe timeline in the year:
1991 AD

It's confirmed to be, at least. after 1989 AD, when the Peachtree Place office building was completed, and before 1998 AD, as that is when Washington National Airport was renamed Ronald Reagan Washington National Airport.
This comic-book was retroactively collected into a "Harbinger" volume 1 subtitled "Children of the Eighth Day" and another subtitled "The Beginning".
It is an early chronological comic-book in the Valiant Universe (a chronologically second comic to feature the Harbinger characters) and can be read at its timeline point.
