Assuming your source data sheets are named as: Sheet1 & Sheet2 (say), both
sheets identically structured with dates in col A, amounts to be summed in
col B

In your summary sheet (another sheet),
In A2 down you have the dates: 12/3/2007, 12/3/2007, etc
You could place in B2:
=SUMIF(Sheet1!A:A,A2,Sheet1!B:B)+SUMIF(Sheet2!A:A,A2,Sheet2!B:B)
Copy B2 down as far as required. Adapt/extend to suit.
