Date object - getting dates of next, previous days

can the date object be used to determine the calendar dates of the days preceding and following today?

i.e.- if i use the date object to return that today is Wednesday, October 10, can i use it to determine that yesterday was October 11 and Tomorrow is October 12?

I need to be able to do this for a custom application that displays info per MTWTF…

i need to be able to have it automatically display real calendar dates (so it knows if it’s the 31st or 28th or whatever and the next day is the 1st).

anybuddy?
