Item #: SCP-3653
Object Class: Keter
Laconic Containment Procedures: Send 1000 D-class away from earth at near-lightspeed, four times per year.
Laconic Description: SCP-3653 is an entity that eats time as it's experienced by humans. It eats more time every year. There are really 572 days in a year, but because of this entity, we only experience 365. We have produced a calendar that can shield a person from this entity, but we only let L4s and O5s use it.
Additional Context: This entry has a dual format, following the "safe but actually keter" trope. The cover entry describes the calendar, which is held in a safe for testing. The "real" entry ("locked" behind a Level 4 restriction) describes the time-eater.
