How to set the first of the week to be Sunday in the Calendar that is displayed in the System Tray of Windows Vista Home Basic. I tried setting the first day of the week to Sunday in Windows Calendar (thinking that it might work) and yet still it displays the first day of the week to be Monday. Moreover there are not settings available on the System Tray Calendar
