Screwy Calendar Behavior!!

[DLCPhoto]

I have a Verizon TP2, Stock ROM, use ActiveSync via WMDC on a 64-bit Vista Home Premium Desktop with Outlook 2003. Starting around the 1st of the year (or at least that's when I noticed it), there has been some really screwy Calendar behavior.

I just completed an ActiveSync (no error messages), and Outlook 2003 on my Desktop shows my wife's birthday as June 1, repeating every year, just as it should.

On my TP2, her birthday shows as every January 1st!!

One of my grandsons has an April 1st birthday, and this now shows up in Outlook 2003 as occurring every 12 years, on April 1, from 1 am to 1 am the next day! On my TP2 it shows correctly on April 1st each year.

This isn't a big issue, but it is perplexing and just plain odd. This doesn't seem like too complicated a task - why does this get so throughly screwed up??
