Fallout 4 starts on October 23, 2287, at the beginning of the game’s opening sequence. This date is fixed in the franchise timeline and marks the moment when the Sole Survivor emerges from Vault 111 to a devastated Commonwealth shaped by the Great War. The choice of this specific date situates the story years after the events of previous titles and establishes the technological and social conditions you navigate from the first hours of the game. Understanding this starting point helps contextualize faction goals, settlement states, and the urgency of the main quest.
Canonical date and timeline placement
The official lore establishes Fallout 4 as beginning on October 23, 2287, which is 210 years after the Great War of 2077. This date is referenced in in-game notes, the Stranger’s dialogue, and codex entries. It follows the arcs of Fallout 3 and Fallout: New Vegas while predating Fallout 76, positioning the Commonwealth as a later but deeply affected region. Because the date is narrative-critical, it remains consistent across main story routes and community consensus.
Narrative significance of the opening day
The opening day introduces you as the Sole Survivor returning to Boston after a day outside the vault. Key beats include escaping Institute pursuit, losing a child, and witnessing the destruction of Sanctuary Hills. These events hinge on the fixed timestamp of 2287-10-23, aligning with long-term plotlines involving the Institute and the Minutemen. Your immediate objectives—to survive, find shelter, and understand the changed world—are framed by this precise starting context.
In-game calendar and time mechanics
While real-time elements like sleeping and fast travel do not strictly map to a persistent calendar, quests and settlement activities often imply progression measured in days or seasons. The starting date is less about clock-time and more about anchoring story beats, character availability, and world states. Recognizing that Fallout 4’s clock is flexible helps you prioritize objectives without worrying about missing a literal October 23 deadline at the outset.
Notable events tied to the starting date
Several key moments in early and mid-game connect to the opening context of October 2287. Factions reference prior incidents, and companion storylines assume recent trauma from the Great War. While player actions can shift regional control and allegiances, the baseline history of the Commonwealth presumes this date as the pivot from pre-war stability to post-war uncertainty.

Player interpretation and common questions
Because the game never shows a calendar interface, some players ask whether they can treat the date flexibly. Story-critical events—Institute attacks, major quest triggers—occur on fixed conditions rather than a real-world day count. Roleplaying around October 23, 2287 enriches immersion but does not gate content; your freedom to explore remains intact regardless of how you contextualize the start date.
Comparisons to other Fallout entries
Unlike Fallout 76, which unfolds in real time around a specific launch-era date, Fallout 4 uses its start date primarily for narrative cohesion. The Lone Wanderer begins in Fallout 3 on a different timeline, while New Vegas emphasizes regional politics more than precise year counts. This focus on aftermath rather than live chronology supports deeper, evergreen explicability of the Commonwealth’s origins.
