December Calendar Puzzle

Did anyone else notice a few of the numbers from the dates in the calendar are bolded? 4, 5 and 18. I didn't see this anywhere else on these forums, so not sure if its nothing or already figured out lol. I assumed it refers to a date: 4/5/18, April 5, 2018? I googled the date and star wars and came up with an old road ahead post from Carrie. Maybe she's coming back? Or maybe I'm just delirious from one too many Profundity event refreshes
