myName:
=OFFSET(Sheet1!$A$1,0,0,COUNTA(Sheet1!$A:$A),COUNT A(Sheet1!$1:$1))

If only for use in VBA, you say 'Select', simply
ws.Range("A1").CurrentRegion.Select

Both the above assumes your first record starts in A1

I want to select the entire contents of a worksheet, but that data set
will change each time I open it as records will be added to it every day.

I want to always choose all records, and there will never be any
non-contiguous rows in the data or blank rows in it.

So I can make a direct call to it and always get all of it by way of
the named range.
