When do CMU Early Decision Admissions decisions release in 2018?

I was looking at the 2017 results and it seems that they were supposed to come out on the 15th and came out on the 10th of December. This year it says that the results will come out on the 15th again but I was wondering if there is any indication of the results coming out earlier? If not, does anyone know what time the results will come out on the 15th? Asking for a friend here…
