# Month before last month?

I use this for the previous month, what would I use for the month before last month?

AND(IFERROR(MONTH(@cell), 0) = MONTH(DATE(YEAR(TODAY()), MONTH(TODAY()), 1) - 1), IFERROR(YEAR(@cell), 0) = YEAR(DATE(YEAR(TODAY()), MONTH(TODAY()), 1) - 1)))

Thank you.

• Hi @Mike Miles ,

=IFERROR(IF(MONTH(@cell)= 1, 11, IF(MONTH(@cell)=2,12, MONTH(@cell)-2)),"")

You'll need to doentify the range for @cell to work.

Help?

• Thanks. I'm actually using SUMIFS to pull data from another sheet that has data by location and date. (multiple years). Here is the formula I'm using for the previous month, which works but I can't figure out how to pull data for the month before last.

=SUMIFS({Data}, {Data Location}, Item@row, {Data Date}, AND(IFERROR(MONTH(@cell), 0) = MONTH(DATE(YEAR(TODAY()), MONTH(TODAY()), 1) - 1), IFERROR(YEAR(@cell), 0) = YEAR(DATE(YEAR(TODAY()), MONTH(TODAY()), 1) - 1)))

Thanks
