Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: Agents have been inserted into several organisations responsible for timekeeping, including the International Time Bureau, the {Cogwork Orthodox} Church, and the International Committee for Weights and Measures. Agents are responsible for preventing possible SCP-XXXX events through stopping any attempts to move the Gregorian calendar forwards in time by any period.
Manifestations of SCP-XXXX events are currently under only partial containment, but due to their inherently antimemetic properties and low danger rating, resources have not been assigned to discovering further manifestations. Additionally, civilian discoveries/rediscoveries of SCP-XXXX manifestations have been deemed useful for finding and possible recruiting individuals with natural/artificial memetic resistance. It is recommended that at least 50 10 1 agent(s) with antimemetic training are monitoring social media for mentions of known manifestations as well as several keywords.
Description:
SCP-XXXX refer to the series of <skipped> time periods caused by the transition from the Julian calendar to the Gregorian calendar, taking place from October 4th 1582 up until February 15th 1923. It is unknown how many of these skipped time periods caused an SCP-XXXX event.
Each known SCP-XXXX event is associated with the antimemetic destruction of a singular location, ranging from sizes of 5 km2 to over {125} km2, the majority of which are located in Eastern Europe. Currently, there are 8 SCP-XXXX locations known to the Foundation (labelled SCP-XXXX-1 through -8), with an estimated 5 to 15 more remaining. All known locations are currently uninhabited and display signs of rushed abandonment.
SCP-XXXX locations are characterised by a strong antimemetic effect that suppresses the recalling of information about the specific area and its contents. This antimemetic effect deteriorates at an unknown rate, theorised to be linked to the length of the associated SCP-XXXX event, the time since the event and the area of the location. This means that while some towns and references to them may be visible to those not under mnestic drugs, smaller objects located within the area are not. Removing objects from the area makes the effect deteriorate measurably faster, but none are safe to view. The antimemetic effect on the locations and their contents is estimated to reach full deterioration by the year 3{125}.
A list of SCP-XXXX locations and notable attributes can be found below, in order of discovery. Some information has been redacted or approximated to reduce the antimemetic influence on this document. Redacted information can be accessed by agents of the Antimemetics Division or <with level 3 security clearance>.
| Designation | Location | Missing Time Period | Discovery | Description |
| SCP-XXXX-1 | Eastern Poland, approximately {3} miles north of {Borowiec} | 1582-10-04 to 1582-10-15 | First known encounter was in 1939 by German forces during the invasion of Poland. Discrepancies were noted when the invading forces detoured around an apparently empty patch of land. | Consists of approximately fifteen (15) <townsteads> with one (1) larger than average church. |
| SCP-XXXX-2 | Southwestern France | 1582-12-09 to 1582-12-20 | Discovered in 1942 by American army project, the {Unthinkables}, later absorbed into the Foundation. Attempts to reuse the location as a military outpost failed due to antimemetic effects. | |
| SCP-XXXX-3 | <Belgium> | 1582-12-20 to 1582-12-31 | [more here] Following the discovery of SCP-XXXX-3, further efforts were placed into finding other SCP-XXXX locations. | |
| SCP-XXXX-4 | <Belgium> | 1583-02-10 to 1583-02-21 | ||
| SCP-XXXX-5 | <Netherlands> | 1582-12-14 to 1582-12-25 | ||
| SCP-XXXX-6 | <Netherlands> | 1583-01-01 to 1583-01-12 | ||
| SCP-XXXX-7 | <Lithuania> | 1585-12-21 to 1586-01-01 | ||
| SCP-XXXX-8 | <any of Poland/Russia/Latvia> | 1617-08-22 to 1617-09-02 |

Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: Any contact with a possible SCP-XXXX entity should be immediately <terminated> and an agent from the Antimemetics Coalition or closest equivalent should be <informed>.
Description: SCP-XXXX refers to one or more unknown antimemetic entities, the existence of which can only be inferred from a series of events (labelled SCP-XXXX-1 through -11), all of which have been disguised through a slowly deteriorating antimemetic effect. This effect is capable of spreading to references to SCP-XXXX locations, albeit the effect is much weaker.

WARNING: The following documents have been recovered from SCP-XXXX locations. As such, they are under much stronger antimemetic effects than the rest of this file. Researchers should be under the influence of at least class X mnestics in order to view and retain knowledge from these files.
Document SCP-XXXX-1-A: [Remember to put "Recovered from church" in table]
Several copies of the 1535 edition Coverdale Bible. An extra chapter is inserted between the Book of Malachi and the Book of Mathew, labelled the Book of [???].
[research some old bibles. Also research bibley language]
[Basically, this should reveal that a whole year is missing between 1 BC and 1 AD]
