It’s a good thing I didn’t solely rely on the LEGO 2016 calendar. Otherwise I could have missed Christmas this year. Check out the month of December 2016.
According to this calendar, Christmas is on a Friday with December 1 falling on a Tuesday. Really though, December 1, 2016 was on a Thursday, and Christmas is on a Sunday. I guess having 11 of the 12 months accurate is good enough?
