156, incorrect day on screen

[Converse]

I have an 03 156 Selespeed veloce. The day given on the console screen is Tuesday the 16th of February. I checked the date settings,they were set to 16-02-2004. Any ideas why it's taking the 16th as being a tuesday? (adds on a day when I take the date back, not sure why I never noticed it!)
