Try something like this:

With
Dates in A1:A40
Values in B1:B40

The total for the month prior to today's month:
C1: =SUMPRODUCT(--(TEXT(A1:A40,"yyyymm")=TEXT(TODAY()-DAY(TODAY()),"yyyymm")))

The total for the year prior to today's year:
C2: =SUMPRODUCT(--(YEAR(A1:A40)=(YEAR(TODAY())-1)))

Does that help?

I have a spreadsheet with column H = date and column J is a numerical

month and also for the last calendar year (Jan1 -Dec 31).

Can anyone help me with this?
