You should take a look at the DateUtils library.

Thanks, I have looked at DateUtils.
What I need to do is:

B4X:

NewDate = (DateTime.Date(DateTime.Now) - 1 day)
etc.

That would give me yesterday

B4X:

    Dim today As Long = DateTime.Now
    Dim p As Period
    p.Days = -1
    Dim newdate As Long = DateUtils.AddPeriod(today,p)
    Log(DateTime.Date(newdate))

Note to check dateutils in libs tab
