How soon does UMCP send out admission letter?

I applied REALLY early and have been doing some research regarding the times when the University of Maryland College Park starts sending out letters. As a senior experiencing high school after a majority of college deadlines have passed, i don't have much to do besides regular senior responsibilities (work, grades, sports, etc). This is generating a lot of anxiety since waiting for such an important letter is very distracting and I am not very patient under these circumstances. So far, i have seen that most letters are released by late January, yet I wanted to know if anyone has experienced an earlier date when they received their letter, possibly mid to late December?
