Yeah, tracking for this month ends today, as it is a four week month and started on the 1st. December will be a five week month.

Results come out on the 10th.

But there's still two days left for this month. I can't see the sense in this.

I think they want to keep the NPD months as 4 weeks-4 weeks-5 weeks, which makes things tidier really. You never get a proper calender month of tracking.
