SCP-XXXX Name: February 30th Object Class: Ticonderoga Special Containment Procedures SCP-XXXX cannot be physically contained, as the anomaly affects the entire baseline reality during its period of manifestation. Foundation efforts are focused on monitoring and damage control during each occurrence of SCP-XXXX. All individuals who retain memories of SCP-XXXX after its termination are to be classified as Class-E Temporal Witnesses and placed under long-term surveillance. Identified witnesses are to be discreetly detained prior to February 29th of leap years and relocated to secure Foundation observation sites. Foundation personnel assigned to SCP-XXXX must avoid engaging in large-scale alterations of reality during the anomaly, as all changes are reverted at termination, making such actions strategically useless. Description SCP-XXXX is a temporal-conceptual anomaly that manifests exclusively during leap years. At 00:00 on February 30th, an otherwise nonexistent calendar date becomes temporarily integrated into baseline reality. During this period, all physical calendars, electronic systems, and human cognition uniformly register the date as February 30th, despite most individuals simultaneously understanding that such a date should not exist. This contradiction is subconsciously dismissed by the human mind, and normal daily behavior continues. The primary anomalous effect of SCP-XXXX is that any consciously imagined desire becomes reality. If an individual thinks of an event, object, or being, it will manifest immediately, regardless of physical, biological, or logical limitations. This includes, but is not limited to: Spontaneous generation of money or resources Resurrection of deceased individuals Materialization of fictional or two-dimensional entities Large-scale alterations to geography or physics As a result, February 30th invariably becomes a global anomic event, characterized by mass reality destabilization, collapse of legal systems, and extreme psychological and social chaos. At 00:00 on March 1st, SCP-XXXX terminates. All reality alterations are fully reverted, returning the world to its exact state at 23:59:59 on February 29th. All individuals lose conscious memory of events that occurred during SCP-XXXX. However, a small, statistically anomalous subset of the population retains partial or complete memory of SCP-XXXX. These individuals often attempt to reproduce outcomes from the anomaly, resulting in erratic or criminal behavior. Addendum XXXX-1: Discovery SCP-XXXX was discovered following a series of unrelated criminal cases involving individuals who claimed that, starting on “February 30th,” they were able to accomplish impossible feats. Subjects independently described identical details of a nonexistent date and unrestricted reality alteration. Foundation investigation confirmed a repeating global temporal anomaly synchronized with leap years. The phenomenon was designated SCP-XXXX after years of confirmation in 20██. Addendum XXXX-2: Testing Protocol Individuals who retain memory of SCP-XXXX are periodically used as temporal anchors. Every four years, selected subjects are placed under controlled observation and instructed to memorize experimental objectives that Foundation researchers intend to perform during the next occurrence of February 30th. When SCP-XXXX ends, subjects are interviewed to reconstruct the events and outcomes of Foundation-directed experiments, allowing partial study of the anomaly despite universal temporal reset." Addendum XXXX-3: Incident Report – “The Continuance Attempt” During the ████ leap year, a coordinated a group of people, who still retain their memories, attempted to prevent the termination of SCP-XXXX. Summary: Subjects attempted to imagine a reality in which March 1st “did not arrive” Several Retainers attempted mass self-sacrifice, believing death during SCP-XXXX would anchor their consciousness beyond the reset One subject attempted to conceptualize “an observer that exists outside time” Result: All attempts failed. At termination, reality reverted as normal. All involved Retainers were returned to life, location, and physical condition prior to SCP-XXXX. Post-event interviews revealed surviving Retainers experienced intense psychological trauma, reporting awareness of “remembering dying multiple times.” Addendum XXXX-4: Theoretical Limitations Analysis indicates SCP-XXXX is not controlled by imagination, but merely responds to it. Key limitations: SCP-XXXX itself cannot be altered The temporal reset is absolute No action taken during February 30th has ever persisted The anomaly appears to function as a closed system, allowing infinite expression but zero escape.
