when did the bombs drop in fallout

In the Fallout universe, the bombs dropped during the Great War on Saturday, October 23, 2077, with the first detonations at about 9:42 a.m. Eastern time.

Core timeline

• The Great War is a global nuclear exchange between the United States and China that effectively ends pre‑war civilization in a matter of hours on October 23, 2077.

• Canon sources and lore breakdowns agree that this single day of strikes—often called “Fallout Day”—is when the iconic mushroom clouds seen across the series occur.

Exact date and time

• The commonly accepted in‑universe answer is that the bombs “fell” on October 23, 2077, marking the start and end of the Great War on the same day.

• A detailed lore timeline places the first confirmed strikes in the U.S. (Pennsylvania and New York) at around 9:42 a.m. Eastern, with other cities like Washington, D.C. and Boston hit minutes later.

Games and show references

• Multiple games—such as Fallout 3, Fallout: New Vegas, Fallout 4, and Fallout 76—reference October 23, 2077 as the day the world ended, reinforcing it as the canonical date.

• The Fallout TV series also centers key pre‑war events around this same date, using the bombs’ fall on October 23, 2077 as its pivotal turning point.

Why fans still debate details

• Fans often discuss who launched the first strike and small timing inconsistencies (for example, how certain scenes line up with local time of day), but these debates do not change the core date and morning timeframe.

• Official material leaves the “who fired first” question deliberately ambiguous, emphasizing that the important lore point is the collapse of global society, not the specific initiator.

In short, when people ask “when did the bombs drop in Fallout,” they are almost always referring to the Great War on the morning of October 23, 2077.
