I hate to continue the speculation, but hey, gotta pass the time somehow, right?
I agree with this for the most part, it clearly has something to do with groups instead of individuals - based on what I've gathered here:
a) Once the date changes to December for the first time, it updates every day after that, so for me it's changed 12/7 through 12/11.
b) After the initial date change, it updates every morning. If it was based on individuals, the date should change at various times through the day
So just to stir the pot, has anyone had a December date change that has not updated through 12/11 at this point?[/quote]
If that happened, I will be shocked. My theory will be disproven!!! Anyone with a date change since 12/7 should have one every morning. You have been pooled!
