Over 30 Michigan schools -- in some part due to fears that the Mayan "prediction" that the world will end on Dec. 21 may come true -- ended the semester two days early, reported NBC News.

An official said that shortened semester was due in large part to the shooting at Sandy Hook Elementary School in Newtown, Conn. -- yet he also mentioned the potential apocalypse. "Additionally, rumors connected to the Mayan calendar predicted end of the world on Friday have also surfaced," he explained, although added it was a "secondary concern."

While rumors of threats or violence at Michigan schools have all been verified as false and officials were reluctant to cut school short, they posed a heavy distraction for the end of the semester. Many parents asserted their children would be kept home regardless of whether school was in session or not, and officials ultimately agreed that the decision was best "given the gravity of recent events and our present circumstances."
