A Most Violent Day
Item#: SCP-XXXX
Object Class: Euclid
Special Containment Procedures:
SCP-XXXX is to be housed in a standard storage room on a steel table. Standard lock and security encryption is to be set on the door and is to be inspected each hour.

If lock is damaged or altered then a standby signal is to be sent to facilities that have objects with the numbers that correlate with the numbers of the month and date. If the door is unlocked then any authorized personnel may enter but may not linger for a period longer than 30 minutes.

Personnel are forbidden to bring any written materials within a 5 meter radius on non-digital mediums as any object that correlates to the written number will immediately breach containment.

Description: SCP-XXXX is a standard two year calendar that always matches the current year. SCP-XXXX-01 is a lock on a door closest in proximity to SCP-XXXX.

SCP-XXXX was first discovered when a Foundation maintenance worker who was inspecting damage after a containment breach entered a storage room and noticed the object. The date was outlined and SCP-████ had broken containment earlier that day. The employee then proceeded to leave but was barred by the storage room door. He then attempted to force the lock and after successfully forcing the aforementioned proceeded to be rendered unconscious and unresponsive. Shortly thereafter SCP-███ breached containment and killed the employee, the object was then quickly contained by MTF-Epsilon 11.

On seemingly random occasions a date will be outlined in red and an object with the correlating number will immediately breach containment and proceed to kill or at least force away any personnel in the immediate area of SCP-XXXX-01.

Any personnel who tamper SCP-XXXX-01 when the object is not unlocked immediately fall into a catatonic state and a short period afterward an object with the correlating number to the offender's month and day of their date of birth will break containment and if possible attempt to kill the offending party.

If any personnel are near SCP-XXXX-01 for a period longer than 30 minutes then the effect is the same as if SCP-XXXX-01 was tampered with.

Addendum XXXX-01:
It is unknown whether SCP-XXXX and -01 are self aware or even alive. But the pair seem to have at least a instinct for self-preservation but how they interpret outside stimuli is thus so far unknown.

Addendum XXXX-02:
It should be noted that tampering with SCP-XXXX-01 and the subsequent containment breach seems to be a self defense mechanism as the object only eliminates the offending party. The relationship between SCP-XXXX and SCP-XXXX-01 seems to be symbiotic, SCP-XXXX-01 seems to be a advanced warning system for SCP-XXXX and the latter provides defense for the former.

Addendum XXXX-03:
Notice to all Site-19 personnel, in light of the recent containment breaches it is now currently forbidden to bring any non-digital mediums such as paper within a five meter radius of SCP-XXXX of its containment area.
