When I used the 21-day season mod, I could arrange things better to my liking. 28 days for one season seems more like the Base game. I get bored of it dragging on and on and on. I make certain that New Year's Eve falls on the same day of the week as Winterfest one week later as it is in my hemisphere. I am aware that those down under celebrate this holiday in the summer. My Sims don't live down under, however. ;) Needless to say, I shall simply roll with it. I just happened to notice it just now and thought I would share.
